Op has said that cutting back to part time means she still has to do same job in less hours. More stress
Can you go back and discuss with your Employer and negotiate a different role? Or ask them can you seek someone else to dig in and take tasks off you? Probably not a runner, don't know the dynamics.
My DH is quite similar at the moment, highly stressed, travel, won't be home till 10 etc he is constantly saying he wants to change which means a fair drop in salary, massive mortgage, 4 kids, I secretly have been going nooooooo but have just supported him and said we will manage if he drops salary, probably would end up selling up and moving smaller. We had our first family holiday only last year so not dripping in disposable.
Since New year he has spoken to boss and re aligned jobs to various other employees, he is home earlier but we will see, I can see it sneaking up again. One year at a time here
I work full time, pay childcare, low stress job, do drop offs, pick up every day but we could not survive on my salary even if no childcare costs
Do you just want out and to be at home as it's so.stressful? I gather by the sounds youd pick something up again no bother in a few years. Career break? Fuck it life's short, I'd fully support my DH even though it would be a bit shit but couldn't see him so stressed, no shagging holiday is worth that
Shake your DHs head and ask him to come up with solutions
