Edit: I have to commute 1,5 hours oneway to get to work. HomeOffice is allowed 2 times a week. So I am leaving when my son is still in bed and come back when he is in bed again. Thing is, the money is good and the job is kind of a dream job for me.
Edit2: Wow! Thank you for your comments. These are exactly the thoughts Inhad in my mind, but couldn’t point my fingers on them. Unfortunately there is no way to get more days wfh, because high management says so. So i came to the descision to either ask for part time or get the new job asap
Moving home is a big ask. Clearly, you like the place as you bought it.
So, maybe asking your management if more WFH is an option. The worst they can say is no, and you will have your answer. From there, if they say yes, you have more time with your son. If they say no, you thank them for considering your request, keep your head down while at work, and quietly look for something more suitable to your lifestyle needs.
It may take a couple of weeks, or it may take a few months. Get paid while you are looking, and do not work until you have that signed employment contract in your hands!
