Inspired by a similar-ish thread on AIBU.
As the title suggests, DP is beginning to get very irate over my occasionally being "late" home from work.
Bit of background and from DP's POV: I work in manufacturing, DP in retail. I work days 7am to 4pm and DP works nights. Because of our working hours, we don't really see each other much during the week but ofc spend all weekend together.
Due to the nature of the job role, DP clocks out bang on finishing time, not a moment later. Never does overtime and doesn't care how this looks to employer. DP doesn't understand why I can't, or rather, choose not to do the same. If I'm in the middle of finishing something off which is time sensitive, I will stay behind the extra 10-15 minutes to get it done and out the way. I'm also conscious of the fact that we (as a workforce) have been threatened with redundancies 4 times over the past 5 years so I also make a point of staying to do certain things so I appear "useful" and valuable to the company. I don't always put in overtime for these extra 15 minutes, although I can if I want to, because I don't want to be seen as taking the piss. DP has the attitude of "fuck them, you finish at 4pm and if something isn't done then it's someone else's problem".
I have a v small commute - 10 minutes - and if im not home by 4.10pm, DP makes snarky comments and quizzes what I've been doing.
Important to note we have no kids, housework is split 70/30 to me, and latest I've ever been home is 4.45pm. Normally its 4.20pm and this isn't every day. Maybe 2 or 3 times a week max.
Am I right in thinking what I do is normal? And that an extra 15 minutes or so isn't a big deal. DP has asked me to put it to MN vote.
