Is it legal for a boss to tell you how you have to cut your hair?

Well it depends on your contract. there are some employer who include changes in your appearance in the contract. but this is mostly about TV journalists or actors etc. If there is a clause in your contract which says that you have to keep your appearance up to some standarts, than, yea it is legal for your boss to tell you how you should cut your hair. you may not do it, because there are also windows in these contract, but it is not illegal for the boss to require certain standart. However, if it is only you who is being told to cut your hair, than you my have a case for the court

yes it's legal , i know many companies which have a dress code , and if u not fit in it , they just tells you it's not gonna happen with them , there is more , some companies don't care if u have ugly hair , ot piercing or tattos , they just wan't to be official , other cares about what hair u'll have , cannot go on biz meeting whit violet hair afterall , but there is people who don't care , it's call democratic :) if u like your self that way nobody can't tell u what to ware
