Legal Question in Employment Law in California

Get serious. I reasonably assume that policy refers to wearing in public, outside your room. And yes, reasonable dress codes are enforceable while you are on company property after you clock out. Since you live on property, guests would recognize you as an employee, even off duty.. In general, unless you are in a union or have a written employment contract, you are an 'at will' employee that can be disciplined or fired any time for any reason, other than illegal discrimination under the Civil Rights, or Whistle-blower, or similar statutes, none of which applies to this situation. Your goal should be to keep your employer happy with you. Following rules tends to do so.
