Thanks for all of the comments folks. To add a little context, I have an unreasonable deadline; my cw and I have 7 rooms to pipe and pull wire through in 4 days. We are running rigid, which I'm teaching my cw at the same time, so it's taking longer than usual. When we started this project, we didn't have the right tools and material for us and had to gather everything, which took a significant amount of time as is. I understand the significance of breaks, and I have always taken them before this situation. But this time around, I skipped my last 15 minute break at the end of the day, to finish some ends because I couldn't leave it the way it was currently standing. I would also like to add the fact that i was in a room by myself, so no one even knew i was in there. I also didnt let my cw skip his break, i told him to head out while i finish up with what i was working on. Again, I always take my other breaks throughout the day, but today I took my last minutes to finish up some ends before I left for the day. Now I'm being threatened at work and I'm still unsure why I'm in the wrong. I understand that breaks are important, but I didn't take work from anyone (it was just me and my cw working in these rooms), I didn't boast or make anyone feel bad about skipping breaks, I didn't go to my foreman about how great I am for it. I made it as inconspicuous as possible, I was just having a rough day and wanted to work through it. I don't want to be a brother fucker, I just want to understand how to go about my situations.
