My company tried to tell me that I had to dress up once. I told them if I was required to dress up then they better plan on cutting me a check. Mandatory=cost covered by company. That shut it down really quick.
Last year everyone in my office dressed up. I wore normal clothes. When people made comments I said 'I'm dressed as a business professional'
Mandatory? my kids would be sick that day
That seems kind of...assholey.
Probably.
I was more business dress then usual.
But it annoys me when people ask 'why aren't you dressed up, why don't you have any Christmas decorations, why don't you have any jelly beans at your desk?'
Obviously it's because I don't want to.
Buut. I can also be an asshole at times. And I'm okay with that.
