Or, what I've heard is
Friday is Hawaiian shirt day. You are required to wear a Hawaiian shirt. That didn't really happen, but it was something similar. My department, to build "team spirit" required everyone to wear a certain color on day... yellow. 1) the color is not one that looks good with all skin tones. 2) I'm one of those people. It makes me look like I need a liver transplant. 3) I own nothing with that color. 4) I and most employees came to work without wearing that color.
When asked, I replied that if I was going to be required to wear a uniform, then I'd expect a uniform allowance. Until then, I was following the organizations dress policy. All it did was fuel resentment instead of team spirit.
When told to stand in a circle and fall back and trust my co-workers to catch me, I refused on the grounds that catching me had nothing to do with their job descriptions, and that while I knew they were good that their jobs and trusted they were trained to answer the phones, file, etc..., I was not confident that they'd been trained in the latest rescue techniques, and I'd require proof of their paramedic licenses. Luckily, the instructor had a good sense of humor.
