Q: Is it "Illegal" to work with a relative as your co-worker or supervisor, or is it left up to the facility/business to make rules regarding how/who they hire as their employees?
There is nothing in California law that prohibits family members from working together. However, many companies institute non-fraternization or anti-nepotism policies as a safety measure to prevent work-place disputes that boil over from non-work relationships as well as to avoid claims of sexual harassment or discrimination. In fact, it is advisable for companies to have such policies.
One of the most problematic areas that arises is when two employees are dating, but the relationship goes sour. As you can imagine, this creates an awkward working environment that will take away from the employees’ productivity, in addition to exposing the company to a sexual harassment claim if one of the employees continues to pursue the other while at work. Also, if the relationship was between a supervisor and a subordinate, the company faces liability if the supervisor favors the person he/she is having the relationship with over other employees when making decisions about bonuses or promotions.
To avoid this problem, many companies have policies in place the either prohibit relationships at work, or some companies require the employees to disclose the relationship. Then the company can work with the employees to see if moving one or both employees to different divisions and/or locations within the company could prevent any potential problems should the relationship not workout in the future. Employers have to walk a fine-line however, because employees have an expectation of privacy about their personal lives while away from work, so employers cannot have too evasive policies. It is best to have a knowledge CA employment lawyer review the policy in advance.
