Some very good points, thanks for sharing them!
I do agree that a "Great Reflection" is coming and workers will not simply accept to revert back to the status quo.
I also think it is important to be very pragmatic about our working arrangements and realise employees have enourmous bargaining power when it comes to determine their working conditions.
I have recently wrote a piece about effectively getting a salary raise (without another offer lined up)

But this can be applied to other aspects of our employment contract such as working hours or flexible location.
