In my office there is no casual wear day, not even friday.
They feel we need to dress professionally at all times.
In my department more specifically we do not often come in contact with the outside but still we need to dress as professional as we can. I'd call our dress code more of casual professional.
Once a year we are permitted to dress casual, for a fee of course. $10 bucks for two weeks.
It is done for charity, the United Way.
I wonder if this policy makes sense to anyone else.
