I used to work for a large company, they often did special things for us to make work a little more enjoyable. Below are a string of memos we received over the course of just over 2 months:
Casual Day Memo No. 1: Effective immediately, the company is adopting Fridays as Casual Day so that employees may express their diversity.
Memo No. 2: Spandex and leather micro-miniskirts are not appropriate attire for Casual Day. Neither are string ties, rodeo belt buckles or moccasins.
Memo No. 3: Casual Day refers to dress only, not attitude. When planning Friday's wardrobe, remember image is a key to our success.
