I would put the United Way #1 on any list of “worst charities” due to the way they infiltrate companies and encourage managers to strong-arm their employees.
At my employer, a day off was used as a bribe if a team had 100% participation in donating to the United Way (minimum $10). I declined, and was the only one on my team to do so. My coworkers put in $5 each to donate in my name so we all got a day off.
That was 2 1/2 years ago, and I still haven’t used that day off.
