Calling all——Working—exclusively pumping mommas

My ultimate was to make it to May (baby girl will be 6 months old) but my small goal was to make it to 3 months. Which we have somehow made it to this goal. But my question is when did you decided enough is enough with work and exclusively pumping.

Little back story—

My daughter had a horrible unexplained latching issue and is also a lazy eater. 3 lactation consultants and one of her pediatricians (also and lc) could not figure out her issue. I then struggled with a low supply but was able to get just enough for her. Low and behold me period came back when she was 8 weeks old supply dip but it recovered, second period now just ended supply is slowly coming back to normal.

But my question is since I’ve been back to work my supervisor tested my ability to stay the first two weeks with nonsense answers that resulted in my going to his boss about lactation breaks and PTO. Before leaving on maternity leave on top of doing my job I was assigned retraining of those people not meeting our set standards. I have been back to work 7 weeks and they are slowly reassigning that to me no biggie but with lactation breaks every 3-4 hours depending on how the day is going I feel like I am doing my trainees a dis-justice. I’m torn what to do I really want to make it to at least May but I also feel this is effecting my ability to do my job. (Nothing has been said to me and I doubt they will say anything but I’m a bit high strung when it comes to my job and my abilities)

So just looking for what every body’s breaking point was (if you had one). Or some ideas on how to make this work at least for 3 more months...
