it's a natural 20

Here there, trying to bring a bit of an answer to your question: what insitives working those essential jobs "down the chain" that aren't obvious to everyone.

I think that first the idea of sharing the load on more ppl so that they don't have to do it all the time is great.

I saw somewhere else for a similar question "make the jobs sexier" as in make them as much enjoyable to do as you can :(some ideas i have but maybe it's not all applicable) personalise the "workplace" and decorate it. Put some speakers so ppl can share their fav musics , make them eat with other ppl from the local community during breaks so that they don't feel lonely/between themselves, create spaces around or within the "factory" where you can do other stuff/hobies. make demonstrations to ppl who don't know the job to raise awesomeness of it. (+ as many ideas as u can think of)

I rlly liked this video, very helpful. it's one of the topics ppl want to talk about first when on the subject of anarchism.
