I’ve seen the same general type of ad for Greenpeace and several other organizations. They all seem too good to be true. I’d love to work for any of these but doing what? Standing on a street corner, trying to raise money from passersby? I don’t think I’d be very good at that. Can’t I just make copies and file and answer phones?
How? Doing what?
Door to door canvassing. You’ll make a very low base pay and then a percentage of what you raise for the week. Some positions might also involve calling people who have donated in the past and asking for new donations.
In the UK there are people paid to stand around busy shopping centres, rail stations and so on trying to sign people up to a regular monthly direct payment. The ‘charity worker’ gets a percentage of the signups.
For some reason the attractive younger women seem to do best 
Ah, thanks dalej42 and trmatthe. Not being an attractive younger woman and being scared to death of door to door canvassing, I guess it’s not for me. Damn. To have an actual job working for gay rights would have been a dream job.
My boyfriend and several other friends worked for one of these. If you don’t meet a minimum quota of donations, you lose the job.
Hmmm.
Did a stint at Ohio Citizen’s Action.
You got 50% of donations 'til your wages hit 12$ or so per hour, at which point your % of the haul went down.
The underlying goal was really getting singular big cash donors on door-to-door canvassing, you you could farm a list of those fat, generous wallets to have experts call from HQ and get large donations out of them.
I sound cynical, but if the organization’s goals are proper, then I don’t consider it a bad operation to be a part of or support.
Mr. Slant, were you the guy who came to my door once and asked me to sign a petition on something? I agreed, and before you handed me the clipboard, you asked me for a contribution. I declined, and then you refused to let me sign. Bastard. It was a good cause, too, whatever it was.
If it wasn’t you, I rescind my epithet and cast it on whoever that guy was.
No, I never did that once to any person of any stripe.
There was a conditional ‘bonus’ for signatures, even without donations, so that would have been counter-productive.
On edit:
Oh yeah, but I AM pretty much a bastard, so your insult is cheerfully accepted.
You certainly use or patronize someone who consumes my current employer’s goods and services, so I’m glad to accept both your insults and your money.
