Any place you work is technically your office, and some people don't follow the dress code.
A father wrote in to Reddit's "Am I The A**hole?" board to inquire whether or not it's okay to fire a babysitter for her clothing...or lack thereof.
Here's how RatherFat explained the situation:
First, I am the father. Second, I do believe that people should be allowed to wear whatever they want, but they can't be free from judgement.
I had this babysitter, Emily, for about a month. She always seemed good, but today I got to leave work early due to a water leak, and came home me about 3 hours earlier. I opened the door, and I see her in just a bra and pants. She was surprised. I payed her for today, and told her that she wouldn't be babysitting our kids anymore.
