I also think my workload and the general culture and balance has much improved as a result of lockdown.
I remember walking to the office in February 2020 and feeling like I was about to cry and give up.
I was exhausted and burnt out. I'd arrive at work and my manager would start asking me questions before I'd taken my coat off. I'd get hammered from all sides, he would agree to get someone from the team to do something for someone else, and our to do list would snowball. We'd be so tied down with extra ad hoc tasks that we'd finally start to do what we'd planned to that day just before 4pm.
People would come over to your desk and tell you they needed X Y and Z ASAP because it was critical to their whole team's work. And they hadn't thought of requesting it in advance - why should they when they can just waltz over and demand you drop all your deliverables for them?
We'd all regularly work an extra 2 or 3 hours a day just to get through everything. We'd log in every Saturday morning from home.
And then COVID hit, and a few things went pear shaped for a few teams. Not because of a drop in productivity, but because the disorganisation and lack of structure which had plagued their teams couldn't survive WFH.
So things changed, and now things go through the proper channels. Of course there are still ad hoc tasks, queries that arise etc. But these are quantified and requested in writing and funded where funding is required.
Things have improved, the workload has improved and the conditions are much nicer.
The thought of going back to that rat race fills me with dread. Everything is so much more managable now. I don't know if I'm more productive, but I do know my work is of a better quality, I can breathe, that I can freely plan to take on more responsibilities and that its rare now for me to be stuck at my desk at 8pm dealing with something that came in at 4pm that's needed by 10am the next morning.
