it's hard to be super specific because so much is contextual from area to area, but for people in the US on this site i think seeing if you have an active PSL or DSA branch in your area and feeling out the work there is a good plan A (EDIT: oh and i think FRSO has a large presence in the midwest).

if you're in a union or you rent in a building with a tenants union, feel out getting more involved in that too/instead. if your coworkers or neighbors seem disgruntled and you don't have either of those things, feel out the possibility of unionizing or forming a tenants union.

but again, these are just common go-tos/"bread and butter" examples of what it means to organize, there are just too many variables to get hyper specific without knowing more about an individual user's situation. i agree that the sentiment without any follow up can be frustrating, though - and agree that snarky quips as responses are especially unhelpful.
