Did some research (read the wiki).

Seems like working at a co-op sacrifices wage stability and maybe wage amount in favor of job-security.

It solves some issues, but gives way to new ones.

While the jobs seem to be more secure, they also grow slower, so hire less.

This suggests to me, that the workload can also vary with the wage.

Overall I wouldn't like it. I like planning my stuff. If once in a blue moon I get layed off, I can make new plans. But adjusting ervery month sounds exhausting.
