highest reputation. You will need to nominate your beneficiaries when you join the scheme.
​
Income Protection Scheme (auto-enrolled)
Sickness absence, particularly if prolonged, poses a serious financial problem for you and those who depend- upon you, as well as for the company. If your sickness absence exceeds that covered by the payments included in the sickness policy stated in your Offer Letter and the Staff Handbook, our policy with Zurich will help us to ensure you continue to receive a percentage of your income if you are unable to work because of illness or injury. This will help to support you during your absence and ease your return to work at the appropriate time. Payments are made in the same way you get your salary, so they will be subject to the same tax and National Insurance contributions.
​
Health Cash Plan (optional)
It is your option whether you join this scheme or not. Further details of the scheme are set out in a separate document available from the Human Resources Manager. At present the Company pays for the employee's entry into Level 2 of the Westfield Chamber Health plan. However, such payment is entirely at the Company's discretion and the Company reserves the right to discontinue, amend or vary any such scheme at any time and will not be liable to provide any replacement benefit of the same or similar kind or compensation in lieu of such benefit. As this is seen (in tax purposes) as a benefit in kind, the payment to the scheme is made via an enhancement of a staff member’s monthly pay by the relevant amount, which is then taxed before a deduction is made from the staff member's monthly salary. It is possible to increase the level of cover under the scheme, but any increase is to be paid for by the member of staff directly and should such payments be required you must authorize such deductions to be made from your salary.
​
Direct Payments to Childcare Providers Scheme (optional)
Certara is  a supporter  of  family  friendly-   working methods.  As such, it is your option whether you join the scheme. Direct Payments to Childcare Providers is a Government initiative designed to support working parents with their childcare costs. This is done via the Busy Bees Childcare Voucher Scheme. This gives an employee a cost saving. Further details can be obtained from the Human Resources Manager.
​
Ride to Work Scheme (optional)
The company has a partnership with Evans Cycles to enable employees to purchase a bicycle and/or equipment to enable them to cycle to work. The scheme offers substantial tax and NI savings of up to 42% on a bike, cycle clothing and equipment, with repayments via a monthly salary sacrifice arrangement.
​
Gymnasium/Sport Club Membership (optional)
You will be eligible to join the Gymnasium/Sport Club Membership scheme. Certara will contribute up to £20 (pre-tax / NI) per month for you to join any gymnasium or sport club in your local area. Details will be provided by the Human Resources Manager during induction.
​
Hours of Work
