In my country of residence, it is not mandatory for employers to offer benefits to their employees. However, if they do offer benefits, then they are not legally allowed to discriminate based on age, gender, race, or marital status.
For family health insurance coverage, my employer will cover the additional fees above single coverage if the employee is married, but not if the employee is in a common-law marriage (my country recognizes common-law marriage as a legal marital status). This policy is in writing. The company may not be aware that this is against the law.
The policy does not affect me directly as of now, but it may affect others in the company, and it may affect me in the future.
The company is small enough that if I found a way to report this anonymously, it would almost certainly be attributed to me. How do I approach this situation without adversely affecting my career with this company?
