Personally, I think Workplace.SE (also in beta) would be an ideal place for working condition questions, if only the question really fit there, which would mean on-site contracted work or something similar.
However, this is for self-employed and freelancing people, so the questions of responsibility for workplace grievances when on-site would be fine here. As would be freelancing from home (as a lot of web developers do).
Moreover, please don't ask "Pros and Cons" (list-type) questions on the Stack Exchange network. We like expert-level, specific questions (heck, we live on them here), and they are warned against in the beta email you received.
