I talked a little bit about this with pderuiter, but our topics were about the use of board members.
What I was suggesting is that HR Manager would be of some use, which in this case is the automatic recruitment of staffs.
I agree though, on the elaboration for subcontractors. If we have a deeper HR aspect, such as unionized labor workforce, this would spawn many interesting things (conflicts, disasters like airport staff on strike, etc.)
However, we have to keep in mind the systems in this game seems like it’s taken from an EU standpoint, and I don’t know if it’s the same case there.
