I cannot stress this enough: YOU TEACH PEOPLE HOW TO TREAT YOU.
It requires a little discipline, and a kind but firm tone, but it's doable.
Shut off all the distractions (I know kids are at home and you can't always) but as far as possible, work in blocks, and apply bum glue so you can get things done.
Because the upside is that when you give yourself time and space to rest and recharge, YOU WORK BETTER AND FASTER AND CAN BE MORE CREATIVE.
I know because I've tried it both way, and had the burnout to prove it.
Here endeth the #WFH thread.
