I plan on retiring as soon as I can get knee surgery done on both my knees under my employer's insurance plan. I started getting medical exams in late 2019 and preparing for the first operation, then the whole COVID thing put those plans on hold. Seems like it's not a good time getting elective surgery when ICUs are full of COVID patients. Plus, I can still hike up the mountain and hunt, so it's not a big deal.
Regarding the work force: I work for a consulting engineering firm (civil, environmental, transportation, industrial). What I've seen is a lot of mid-level staff move on to other firms, as my employer has been giving most everyone basically cost-of-living (2-3%) annual raises. So we have a lot of junior staff and a lot of senior staff. This is not good.
I still enjoy working on my technical work, but in the last couple of years, in order to improve profitability, my firm has adopted project management guidance from the Project Management Institute as requirements for managing projects, including having the project managers (self included) become certified Project Management Professionals. This is the biggest scam I have ever seen. Someone is getting rich on this malarkey.
