One of the many challenges of working for a family owned business.
Been there and done that myself and you are correct. Family members got off every Friday and unlimited vacation while all others got one week vacation and no sick leave, paid themselves 4-5 times what the highest non-family members got paid and they all had company owned cars. Net result- they ended up stealing all the money, bankrupted the company and still living fat and happy while most of the employees suffered, fortunately I had long sine left before that happened. been over 30 years ago but I have never forgotten all the bullshit they pulled on everybody. No desire to ever work for someone else's family again.
