I stopped giving to the United Way about 10 years ago. Before that, I was afraid not to give because of the intracompany pressure to give, and the fact that they keep track of the giving, at least insofar as reporting whether everyone gave SOMETHING. They wanted 100% participation, so I always gave $50 or thereabouts. At some point, I just got to a point where I said, "I'm not going to let my employer tell me who to give my charitable contributions to."
I'm still working for the company.
I experienced the same thing when I went to work for the old Southwestern Bell Telephone. In the early 70s men were being hired into traditional women's positions. I started out as an operator.
100% was the goal and the pressure was designed to reach that goal. I simply said that I had just returned from being shot at for a year and there wasn't a %$(*^%$ way I was going to be pressured into a damn thing.
After that I became vocal to everyone about the UW and the 100% goal was sacked.
