I know quite a few people who've called it a day during the pandemic, often people whose already stressful jobs became more so as a result (three headteachers!) But I also know people who thought they'd give up about now, but now they're working from home have decided to stay a bit longer.
I also know one man who'd arranged to go to 3 days pw as part of a phased retirement, but has put that off for now because he didn't see the point of having more free time to spend in lockdown and/or unable to travel.
I'm at an age where I could go now or could work for another 15 years (or more) and I am finding myself increasingly less motivated, but still not quite ready to stop. I think the change to motivation is in large part due to the changes caused by the pandemic.
