Before the referring court, the Ministry claims that Directive 1999/70 does not apply since it concerns only working conditions and not forms of administrative status.

| 20 | The Ministry explains that if Ms Vega González was an established civil servant she would have been granted the special service leave referred to in Article 59 of Law 3/1985, the employer authorities having no discretion in that regard. Thus, the only way for Ms Vega González to carry out her political duties full time would be to resign from her post permanently. |

Thus, the only way for Ms Vega González to carry out her political duties full time would be to resign from her post permanently.

| 21 | The referring court notes that, in accordance with the Court’s settled case-law, a difference in treatment with regard to employment conditions as between fixed-term workers and permanent workers is not compatible with the requirements of Directive 1999/70, unless it is justified by objective reasons. |

21

The referring court notes that, in accordance with the Court’s settled case-law, a difference in treatment with regard to employment conditions as between fixed-term workers and permanent workers is not compatible with the requirements of Directive 1999/70, unless it is justified by objective reasons.

| 22 | In that regard, the referring court maintains that, even if it is theoretically possible to argue that the difference in treatment is justified by objective reasons relating to the necessity and urgency for making the temporary appointment, that argument does not, however, apply in a situation in which the post has been occupied by a temporary worker for more than four years. In addition, the referring court notes the particular importance of the right in question, namely the right of access to public office, which is guaranteed by the Spanish constitution. |

In addition, the referring court notes the particular importance of the right in question, namely the right of access to public office, which is guaranteed by the Spanish constitution.

| 23 | According to the referring court, the temporary nature of the activity carried out by a non-established civil servant is not, in itself, an objective reason justifying a difference in treatment that deprives him of the right to return to his post at the end of his parliamentary term of office. Even though, during that term of office, the possibility of reinstatement might de facto be lost on the grounds that the post that the temporary agent occupied was, in the intervening period, filled by an established civil servant or was simply abolished, it also cannot be ruled out that the situation which justified the appointment of that non-established civil servant might still exist at the end of his parliamentary term of office. |

Even though, during that term of office, the possibility of reinstatement might de facto be lost on the grounds that the post that the temporary agent occupied was, in the intervening period, filled by an established civil servant or was simply abolished, it also cannot be ruled out that the situation which justified the appointment of that non-established civil servant might still exist at the end of his parliamentary term of office.

| 24 | Therefore, the referring court’s doubts mainly concern the concept of ‘working conditions’ for the purpose of Clause 4(1) of the framework agreement. It states that, as it stands, the Court has examined the scope of this concept only with regard to matters of remuneration to be received, working time, the working day, the calendar or holidays, or indeed, more generally, leave that may be given for absence from work. It is therefore necessary, first, to determine whether the concept of ‘working conditions’ also covers the obligation to place a fixed-term worker, in the present case a non-established civil servant, onto an administrative status which allows him, as it does a permanent worker, namely an established civil servant, to suspend the employment contract in order, specifically, to fulfil a political mandate for which he has been elected. Second, the referring court is uncertain whether the difference in treatment, made by Article 59 of Law 3/1985, between non-established civil servants and established civil servants is compatible with the principle of non-discrimination established in Clause 4(1) of the framework agreement. |

| 25 | It is in those circumstances that the Juzgado de lo Contencioso-Administrativo n.1 de Oviedo (Administrative Court No 1, Oviedo) decided to stay the proceedings and refer the following questions to the Court for a preliminary ruling:





  ‘(1) | Must the term “employment conditions” in Clause 4 of the framework agreement be interpreted as including a legal situation in which a fixed-term worker who has been elected to political office as a member of Parliament may, in the same way as a permanent member of staff, apply for and be granted a break in the service relationship with the employer so as to be reinstated in the same post once the relevant parliamentary term of office has expired? |

| (2) | Must the principle of non-discrimination referred to in Clause 4 of the framework agreement be interpreted as precluding national legislation such as Article 59(2) of Law 3/1985, which totally and absolutely precludes giving a “non-established” civil servant special service leave in the event of being elected a member of Parliament, when that right is given to “established” civil servants?’ |

The first question

The first question

| 26 | By its first question, the referring court asks, in essence, whether Clause 4(1) of the framework agreement must be interpreted as meaning that the concept of ‘employment conditions’, referred to in that provision, includes the right for a worker who has been elected to a parliamentary role to benefit from special service leave, provided for by national legislation, under which the employment relationship is suspended such that the worker’s job and his entitlement to promotion are guaranteed until the end of his parliamentary term of office. |

| 27 | As a preliminary remark, it must be borne in mind that, as provided in Clause 1(a) of the framework agreement, one of the agreement’s objectives is to improve the quality of fixed-term work by ensuring the application of the principle of non-discrimination. In addition, the third paragraph of the preamble to the framework agreement states that the agreement ‘illustrates the willingness of the Social Partners to establish a general framework for ensuring equal treatment for fixed-term workers by protecting them against discrimination’. Recital 14 of Directive 1999/70 states, to that effect, that the aim of the framework agreement is, in particular, to improve the quality of fixed-term work by setting out minimum requirements in order to ensure the application of the principle of non-discrimination (judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 25 and the case-law cited). |

| 28 | The framework agreement, in particular Clause 4, aims to apply the principle of non-discrimination to fixed-term workers in order to prevent an employer using such an employment relationship to deny those workers rights which are recognised for permanent workers (judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 26 and the case-law cited). |

| 29 | Having regard to the objectives pursued by the framework agreement, Clause 4 of that agreement must be understood as expressing a principle of EU social law which cannot be interpreted restrictively (judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 27 and the case-law cited). |

| 30 | With regard to the concept of ‘employment conditions’ within the meaning of Clause 4(1) of the framework agreement, the Court has already held that the decisive criterion for determining whether a measure falls within the scope of that concept is, precisely, the criterion of employment, that is to say the employment relationship between a worker and his employer (judgments of 12 December 2013, Carratù, C‐361/12, EU:C:2013:830, paragraph 35; of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraph 25; of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 26; and order of 9 February 2017, Rodrigo Sanz, C‐443/16, EU:C:2017:109, paragraph 32). |

| 31 | The concept of ‘employment conditions’, within the meaning of Clause 4(1) of the framework agreement, thus covers three-yearly length-of-service increments (see, to that effect, judgment of 13 September 2007, Del Cerro Alonso, C‐307/05, EU:C:2007:509, paragraph 47; of 22 December 2010, Gavieiro Gavieiro and Iglesias Torres, C‐444/09 and C‐456/09, EU:C:2010:819, paragraphs 50 to 58; and of 9 July 2015, Regojo Dans, C‐177/14, EU:C:2015:450, paragraph 43), six-yearly continuing professional education increments (see, to that effect, order of 9 February 2012, Lorenzo Martínez, C‐556/11, not published, EU:C:2012:67, paragraph 38), rules concerning periods of service to be completed in order to be classified in a higher salary grade or calculation of the periods required to have performance assessed each year (see, to that effect, judgment of 8 September 2011, Rosado Santana, C‐177/10, EU:C:2011:557, paragraph 46 and the case-law cited), the right to participate in a teaching evaluation plan and the ensuing financial incentive (order of the Court of 21 September 2016, Álvarez Santirso, C‐631/15, EU:C:2016:725, paragraph 36), as well as the reduction of working hours by half and the consequent reduction in wages (order of 9 February 2017, Rodrigo Sanz, C‐443/16, EU:C:2017:109, paragraph 33). |

The concept of ‘employment conditions’, within the meaning of Clause 4(1) of the framework agreement, thus covers three-yearly length-of-service increments (see, to that effect, judgment of 13 September 2007, Del Cerro Alonso, C‐307/05, EU:C:2007:509, paragraph 47; of 22 December 2010, Gavieiro Gavieiro and Iglesias Torres, C‐444/09 and C‐456/09, EU:C:2010:819, paragraphs 50 to 58; and of 9 July 2015, Regojo Dans, C‐177/14, EU:C:2015:450, paragraph 43), six-yearly continuing professional education increments (see, to that effect, order of 9 February 2012, Lorenzo Martínez, C‐556/11, not published, EU:C:2012:67, paragraph 38), rules concerning periods of service to be completed in order to be classified in a higher salary grade or calculation of the periods required to have performance assessed each year (see, to that effect, judgment of 8 September 2011, Rosado Santana, C‐177/10, EU:C:2011:557, paragraph 46 and the case-law cited), the right to participate in a teaching evaluation plan and the ensuing financial incentive (order of the Court of 21 September 2016, Álvarez Santirso, C‐631/15, EU:C:2016:725, paragraph 36), as well as the reduction of working hours by half and the consequent reduction in wages (order of 9 February 2017, Rodrigo Sanz, C‐443/16, EU:C:2017:109, paragraph 33).

| 32 | The Court has also held that rules for determining the notice period applicable in the event of termination of fixed-term employment contracts form part of ‘employment conditions’ within the meaning of Clause 4(1) of the framework agreement (see, to that effect, judgment of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraphs 27 and 29). |

| 33 | This is also the case with the compensation that the employer must pay to an employee on account of the unlawful insertion of a fixed-term clause into his employment contract (see, to that effect, judgment of 12 December 2013, Carratù, C‐361/12, EU:C:2013:830, paragraph 37) or following termination of fixed-term employment contracts (see, to that effect, judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 31). |

| 34 | As was noted by the Advocate General in point 22 of her Opinion, the expression ‘employment conditions’ should be understood to mean the rights, entitlements and obligations that define a given employment relationship, including both the conditions under which a person takes up employment and those concerning the termination of that relationship. |

| 35 | A decision granting special service leave, such as that at issue in the main proceedings, which leads to the suspension of certain elements of the employment relationship whilst others are maintained, must, therefore, be deemed to satisfy the criterion set out in paragraph 30 of the present judgment and accordingly to fall within the concept of ‘employment conditions’ within the meaning of Clause 4 of the framework agreement. |

A decision granting special service leave, such as that at issue in the main proceedings, which leads to the suspension of certain elements of the employment relationship whilst others are maintained, must, therefore, be deemed to satisfy the criterion set out in paragraph 30 of the present judgment and accordingly to fall within the concept of ‘employment conditions’ within the meaning of Clause 4 of the framework agreement.

| 36 | Indeed, it is not disputed that the decision to grant such leave to a worker is necessarily taken on the basis of the employment relationship which connects him to the employer. Moreover, it must be noted that, in the present case, the special service leave provided for by Law 3/1985 not only leads to the suspension of the employment relationship but also allows for the worker’s place of employment to be reserved until his reinstatement at the end of his parliamentary term of office, ensuring that it is included for the purposes of calculating three-yearly length-of-service increments and promotion in grade — matters which have already been expressly recognised, as is clear from the case-law cited in paragraph 31 of the present judgment and as the Advocate General notes in point 25 of her Opinion, as falling within the definition of ‘employment conditions’. |

| 37 | The argument that, in the context of the dispute in the main proceedings, the need to be granted such special service leave is a result of the deliberate and unilateral decision of the fixed-term worker to take part in the elections is not decisive in this respect, since a permanent worker in the same situation would have been faced with the same need. Furthermore, a person who puts themselves forwards for a parliamentary role is not guaranteed to be elected, such that merely the fact, in itself, of putting themselves forward does not require them to request special service leave. |

| 38 | In any case, it should be added that an interpretation of Clause 4(1) of the framework agreement which excludes from the definition of ‘employment conditions’ the right to special service leave would limit the scope of the protection granted to fixed-term workers against discrimination, in disregard of the objective pursued by that provision (see, to that effect, judgments of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraphs 27 and 29 and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 30; as well as order of the Court of 21 September 2016, Álvarez Santirso, C‐631/15, EU:C:2016:725, paragraph 39). |

| 39 | Therefore, the answer to the first question must be that Clause 4(1) of the framework agreement must be interpreted as meaning that the concept of ‘employment conditions’, referred to in that provision, includes the right for a worker who has been elected to a parliamentary role to benefit from special service leave, provided for by national legislation, under which the employment relationship is suspended such that the worker’s job and his entitlement to promotion are guaranteed until the end of his parliamentary term of office. |

The second question

The second question

| 40 | By its second question, the referring court asks, in essence, whether Clause 4 of the framework agreement must be interpreted as precluding national legislation, such as that at issue in the main proceedings, that absolutely excludes fixed-term workers from the right to be granted leave, so that they may hold political office, during which the employment relationship is suspended until the worker’s reinstatement at the end of the term of office, when that right is conferred on permanent workers. |

| 41 | With regard to Clause 4 of the framework agreement, it must be noted that its first paragraph lays down, in respect of employment conditions, a prohibition on treating fixed-term workers in a less favourable manner than permanent workers in a comparable situation solely because they have a fixed-term contract, unless different treatment is justified on objective grounds. |

With regard to Clause 4 of the framework agreement, it must be noted that its first paragraph lays down, in respect of employment conditions, a prohibition on treating fixed-term workers in a less favourable manner than permanent workers in a comparable situation solely because they have a fixed-term contract, unless different treatment is justified on objective grounds.

| 42 | According to the Court’s settled case-law, the principle of non-discrimination requires that comparable situations must not be treated differently and that different situations must not be treated alike unless such treatment is objectively justified (judgments of 8 September 2011, Rosado Santana, C‐177/10, EU:C:2011:557, paragraph 65 and the case-law cited, and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 35). |

42

According to the Court’s settled case-law, the principle of non-discrimination requires that comparable situations must not be treated differently and that different situations must not be treated alike unless such treatment is objectively justified (judgments of 8 September 2011, Rosado Santana, C‐177/10, EU:C:2011:557, paragraph 65 and the case-law cited, and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 35).

| 43 | In the present case, it must be held that there is a difference of treatment between fixed-term workers and permanent workers, since a permanent worker, elected to political office, may be granted special service leave under which the employment relationship is suspended until the worker’s reinstatement at the end of the term of office, whilst a fixed-term worker must resign from his post in order to hold the same office. |

In the present case, it must be held that there is a difference of treatment between fixed-term workers and permanent workers, since a permanent worker, elected to political office, may be granted special service leave under which the employment relationship is suspended until the worker’s reinstatement at the end of the term of office, whilst a fixed-term worker must resign from his post in order to hold the same office.

| 44 | Thus, it is only if the work carried out by a worker such as Ms Vega González within the context of her fixed-term contract is not identical or comparable to the work carried out by permanent workers that the alleged difference in treatment with respect to the right to be granted special service leave may be justified, notwithstanding the prohibition set out in Clause 4 of the framework agreement, as that difference in treatment would relate to different situations (see, by analogy, judgments of 18 October 2012, Valenza and Others, C‐302/11 to C‐305/11, EU:C:2012:646, paragraph 48 and the case-law cited, and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 41). |

| 45 | In order to assess whether the persons concerned are engaged in the same or similar work for the purposes of the framework agreement, it must first be determined, in accordance with clauses 3(2) and 4(1) of that agreement, whether, in the light of a number of factors such as the nature of the work, training requirements and working conditions, those persons can be regarded as being in a comparable situation (judgments of 18 October 2012, Valenza and Others, C‐302/11 to C‐305/11, EU:C:2012:646, paragraph 42 and the case-law cited; of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraph 31; and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 40). |

45

In order to assess whether the persons concerned are engaged in the same or similar work for the purposes of the framework agreement, it must first be determined, in accordance with clauses 3(2) and 4(1) of that agreement, whether, in the light of a number of factors such as the nature of the work, training requirements and working conditions, those persons can be regarded as being in a comparable situation (judgments of 18 October 2012, Valenza and Others, C‐302/11 to C‐305/11, EU:C:2012:646, paragraph 42 and the case-law cited; of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraph 31; and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 40).

| 46 | It is therefore for the referring court to determine whether Ms Vega González is in a situation comparable to that of workers employed on a permanent basis by the same authority for the same period (see, by analogy, judgments of 18 October 2012, Valenza and Others, C‐302/11 to C‐305/11,EU:C:2012:646, paragraph 43 and the case-law cited; of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraph 32; and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 42). If, on completion of that assessment, the referring court finds inequality of treatment, it would then have to ascertain whether it may be justified on ‘objective grounds’ within the meaning of Clause 4(1) of the framework agreement, that is to say, by precise, specific factors, characterising the employment condition in question, in the particular context in which it occurs and on the basis of objective, transparent criteria that enable it to be ascertained whether that unequal treatment in fact meets a genuine need, is appropriate for achieving the objective pursued and is necessary for that purpose (see, to that effect, judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 45 and the case-law cited). |
| --- | --- |

46

It is therefore for the referring court to determine whether Ms Vega González is in a situation comparable to that of workers employed on a permanent basis by the same authority for the same period (see, by analogy, judgments of 18 October 2012, Valenza and Others, C‐302/11 to C‐305/11,EU:C:2012:646, paragraph 43 and the case-law cited; of 13 March 2014, Nierodzik, C‐38/13, EU:C:2014:152, paragraph 32; and of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 42). If, on completion of that assessment, the referring court finds inequality of treatment, it would then have to ascertain whether it may be justified on ‘objective grounds’ within the meaning of Clause 4(1) of the framework agreement, that is to say, by precise, specific factors, characterising the employment condition in question, in the particular context in which it occurs and on the basis of objective, transparent criteria that enable it to be ascertained whether that unequal treatment in fact meets a genuine need, is appropriate for achieving the objective pursued and is necessary for that purpose (see, to that effect, judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 45 and the case-law cited).

| 47 | In that regard, the Court has already held that the concept of ‘objective grounds’, within the meaning of Clause 4(1) of the framework agreement must be understood as not permitting a difference in treatment between fixed-term workers and permanent workers to be justified on the basis that the difference is provided for by a general, abstract national norm (judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 46 and the case-law cited). |

| 48 | Moreover, it is also clear from the Court’s established case-law that reliance on the mere temporary nature of the employment of staff of the public authorities does not meet those requirements and cannot constitute an ‘objective ground’ for the purposes of Clause 4(1) of the framework agreement (judgment of 14 September 2016, de Diego Porras, C‐596/14, EU:C:2016:683, paragraph 47 and the case-law cited). |

| 49 | In the present case, even if the referring court does not rule out that the necessity and urgency of making a temporary appointment, like the predictability of the end of the employment relationship, could, in principle, constitute precise and concrete factors capable of justifying inequality of treatment as regards the granting of special service leave, it states, however, that such arguments do not apply in a situation such as that giving rise to the dispute in the main proceedings where the post has been occupied for more than four years by the same temporary worker. |

| 50 | In any case, the absolute refusal to grant fixed-term workers special service leave does not prima facie appear to be indispensable to the objective pursued by Law 3/1985, namely the maintenance of jobs and the entitlement to promotion of permanent workers — and more specifically established civil servants holding political office — in as much as the referring court itself considers it entirely feasible that fixed-term workers holding a similar office could be granted special service leave that suspends the employment relationship until the end of that term of office at which time they would be guaranteed reinstatement to their post, provided it had not, in the meantime, been abolished or filled by an established civil servant. |

| 51 | In view of the above, the answer to the second question must be that Clause 4 of the framework agreement must be interpreted as precluding national legislation, such as that at issue in the main proceedings, that absolutely precludes granting a fixed-term worker, so that they may carry out a political mandate, a leave during which the employment relationship is suspended until the worker’s reinstatement at the end of the term of office, when that right is conferred on permanent workers. |
