I've seen parents who negotiate hard for three days a week get it, but they are quickly 'mommy tracked' and stop getting promotions. Additionally when a crisis at work happens on their off day, they still get the call.
I think a tech company that figures out how to make part-time jobs work culturally will have a huge recruiting and talent advantage, especially this year. I haven't seen it pulled off yet though.
I'm going to ask you to clarify this.
In my experience, medical professions are LOUSY for "part time". You are on horribly long shifts. They move around continuously. You have no control over your shifts until you get to a very significant level of seniority.
And, right now, you're on the front lines of a pandemic.
The only advantage to something like nursing (at least it used to be) is that no matter where your spouse is, you will have work.
Unfortunately, in most companies this is not an option. Full time (and be happy if this doesn't include overtime) or go away. And I can't afford to go away.
