I didn’t read all of the posts here but if you work for a company that is large enough to have an HR department it should be brought up to them. No one should be pressured to participate in ANY sort of fundraising. The company I work for is very specific about this. People can/do leave sign up sheets in the common break room for Girl Scout cookies, Boy Scout Popcorn, charity walks , etc which is fine. But no one is directly asked/approached to give.
