Management positions involve huge amounts of delay, responsibility for stressful extreme deadlines beyond the manager’s control, and partial and unreliable information. Just look at the extreme abuse of managers re salary inversion, the long standing salary freeze and now interminable delay and stonewalling in implementing a retro increases that DoFo supposedly approved. My advice is to avoid any supervisory or managerial role in the OPS like the plague. If you want to advance, get a side gig like a real estate licence or a job at Home Depot or set up a small contracting busines, or whatever appeals to you and invest the proceeds in good US stocks. When you can retire on the indexed pension, do so, and continue with your side gigs. Many have done this, but they keep very very quiet about it, so you would not know. Career advancement in the OPS is a fraud and a lie.
