"Last year, the entire office wore denim and everyone who wore jeans contributed $2. It was nice to wear jeans and be a part of something bigger."
If you're looking for a reason to have "Casual Friday" on a Wednesday, this is it! Get the boss involved and have fun. Offer the opportunity to donate a few dollars to wear jeans then donate the funds to survivors through LaFASA.
Does your company have multiple locations? Have a contest. See who can get more people to wear jeans and see who can get the bigger monetary contribution!
