I don’t know where you’re getting the work is light part. It’s long hours and incredibly stressful work. You’ll probably never hit this level of stress in years of trades work.
I would invite you to come experience the trades for a bit, particularly in senior positions.
Having worked at two big tech companies, I’d say one was the most laid-back, stress free environment I’ve ever worked in, and the other was pretty middle of the road.
It is obviously a range. Most of my personal firends work a couple hours a day and get pampered.
it's pretty team/org dependent. on the aggregate i suspect big tech works pretty light hours compared to other jobs in the same pay scale
