I have a right to not wear dockers

So at my current permalance gig, the company was just just purchased by another company. There is a new policy (among others) that a dress code of “business casual” is to be enacted as of May 1st. Well, I am thinking of protesting. It seems rediculous in this day and age to make people go out and spend money on clothes they wouldn’t normally wear. I say no to dockers.
