The UW is another bureaucracy whose purpose is to give to another charity? Why not give it to the charity directly? Any recent moves by UW to imply that the money they take will be forwarded in toto to a designated charity is an ADMISSION that such is not the typical practice of UW. UW talk about "no overhead" is a direct ADMISSION of the redundancy of UW. I suspect UW says such things now because people in general are becoming more aware of direct distributions and "overhead" i.e., bureaucracy expenses/taxation. (I am at least)
Additionally, looking at the UW types, I feel many are corporate board rejects, and UW is kind of a nepotisitic depository for types who don't fit in, can't cut it, or can't get with the program. Welfare for incompetents, their salaries paid by a sort of second taxation on charitable giving.
If corporations and businesses are so committed to the concept, let them write a check instead of having the HR department act as bagmen.
