Pros
The shift supervisor role consists of busy days with a lot of varying priorities. You are responsible for emissions regulation, work permits, specialized permits, managing changing plant conditions, and administrative personnel requirements. This can be a high-octane role but has a more relaxed period on night shift and when outages aren't occurring (planned shutdowns for maintenance). Expect to drive plant performance and employee development. Many opportunities for professional and personal development if you put the time in.
Cons
The plant culture will play a huge role in your quality of life, since most of your time will be at the plant. This can be good or bad. Quite a few managers do not engage or develop personnel due to various qualities. You will have to do the leg work in fostering a change for personnel development.
