In one of my first jobs I negotiated less hours instead of a raise whenever I got offered a raise. I went from 40 hours/week to 36 hours/week to 32 hours/week in a few years.
I, for one, am not talented at what I do, and have no power in any negotiation. I couldn't even negotiate salary, since I offer literally nothing no one else couldn't offer.
If the workplace mirrored the animal kingdom, I am more of the type of animal that feasts on carrion than hunts for fresh prey. Thus, I would never be able to swing such a deal.
However, I do hope those that can swing such a deal do so, so that it may systemically trickle down to us scavenger type.
If you absolutely can not relocate, then remote is a condition, and you will turn down any offer that is not remote.
If you absolutely can not take a pay cut, then a certain salary is a condition, and you will turn down any offer that is less than you currently make.
If you absolutely want to work four days a week, then part time is a condition, and you will turn down any offer that is not four days a week.
It's likewise in how I was willing to relocate 5 years ago for my first job. Because I wanted to take any opportunity and many others would pass me over. There's enough supply and enough talent on my end that I no longer need to relocate (plus I lucked out into a house. I'd need to literally triple my salary to justify moving and maintaining this kind of QoL if I was recruited into Silicon Valley), but I haven't seen the same prospects with part time, decently compensated tech work. I've looked out of curiosity due to long term plans, but it doesn't seem to be publicly advertised.
