UFCW, SEIU, and UNITE-HERE might want someone to work an "unskilled" job depending on the local.
Depending on what part of environmentalism you're in, there's lab scientist, political organizer and landscaper unions in some places.
As a heads up, working for a union at the lowest level is basically the same experience as working at a "mission-driven" non-profit: you're expected to work for more hours than you're paid for, for "the cause", then burn out and quit after a few years. This is by design, it's how they deal with small budgets and an enthusiastic (exploitable) workforce.
Some of them even promote this while raising the pay and time off for the higher-up bureaucrats. UFCW is one such example. A fairly crap union that I steer everyone away from.
Understandable, stay safe comrade!
