Well...if you work for an employer and they care, you're kind of stuck with your employer. You might not care but your employer does. And that leaves you with a decision - stay working at a place that cares about things you don't care about or leave that place for an employer who only cares about what you care about.
You're a grown up. You know how this works. I think it's inane when adults who live in a world where they know that they are beholden to the positions and wishes of other people pretend that they're free to ignore other people's wishes but still reap the benefit of the relationship.
I don't care about wearing a tie to court but every judge does care. So, if I want the benefit of the judge's goodwill, I adhere to the judge's preferences, regardless of my personal feelings. If I really feel strongly about the tie thing...I stop taking cases that require me to go to court.
If you don't like what someone else likes, that's fine. But you don't get to keep the benefit of the relationship and ignore their preferences. No one is forced to associate with others. Even if the choice is a tough one, the choice still exists. It ends up being a matter how much you really don't care.
Back to the workplace, if you don't care and your employer does, it shouldn't bother you to follow through on their wishes...you don't care either way, right?
