Original sentence: A number of arguments have been raised against these proposals.Another concern which has been raised is the possibility that rabbinical authorities may become legally culpable for accidents that occur in environments which they have previously certified as safe; related to this is the concern that there is currently no concretely proposed mechanism for monitoring the employer's continued compliance with the certification, particularly with things like the Heksher Tzedek where there is a need to monitor a vaguely defined quality - the fairness of the employer.However this information is never made transparent to consumers through certification or product markings.In Israel, a new movement has gone further, demanding that food-selling establishments (grocers and restaurants) should only be considered fully kosher if their employees are paid a decent wage and treated fairly, and if the buildings have access for the handicapped; the movement envisage this as requiring an additional second certificate of kashrut, rather than as replacing the standard certification.Several critics of the suggestions believe that entities providing Kashrut certification shouldn't be involved in the politics of labour.The Rabbinical Assembly, the USA's association of rabbis in Conservative Judaism, has endorsed a proposed certification, called Heksher Tzedek, which would signify that food was produced under safe and just working conditions; the specific requirements for implementing the certification remain under development, but the current plan is for it to be an additional certification, rather than a replacement for kosher certification.The labour laws of different countries can vary widely in the extent to which they directly benefit the employee's welfare, rather than the employer's income, but certain critics believe that their country's laws about labour still would not need supplementation by rabbinic certifications; for example, a number of Rabbis have argued that the laws of the USA already include labour regulations matching those of the Torah, and provide several mechanisms for individuals to report and prosecute breaches of these laws
