First we must admit that as humans, we deserves to do our jobs earnestly as long as we get paid for it. Also the other side, nomatter how flexible humans maybe tasked on their respective work places, they will surely complains with excuses.

That is humans for all. We don't ever get satisfied neither grateful where there is no sign of changes in our designated work places.
Some may not be contended with their positions and some get weird of attending and doing usual tasks while some kicks against their review of payments (salary's when they job see getting tough to them). We just love to try something unusual to see how it fells or if we are going to get better results or comforts.

Also is why those working from home (remote workers) want to work from the offices due to boredom of monopoly fatigues while operational field workers feel exhausted and wish they could have their jobs done with some ease of flexibilities.

It all course we feel that burnouts and that is human nature.
That is why if a hardworking man is asked to stay at home, do nothing and just get paid for doing nothing, he will still demand to atleast do something to see his efforts put to work is the source of his incomes and while just tested the water, he would feel good nomatter the condition but once full commitments has been applied he would anticipate to opt out.

Humans can not just get a whole satisfaction.
