Been watching this thread and saw that you were a carpenter, thought about responding then but try not to talk shop. That's how I started, residential framing. Did my apprenticeship and was union and non union for over 10 yrs.
Coming from the trades, I know what it's like to get burned and make it a point not to treat my guys that way. That usually comes from the top, some project manager barking that you have to get it started whether you're ready or not. Some super's don't have the balls to tell them no, especially the green horns so they go ahead and make that call.
Keep in mind it goes the other way too though. Trades telling me they'll be ready several weeks in advance and then don't show. Tell my guys out of the gate, you can BS the white collars but don't BS me. Hell I'll even cover for you if you're going to be a little late finishing another job. They know if they lie to me they're going to lose their a**.
Handling critical situations in a high pressure atmosphere is the hardest part of the job. Had a couple foreman's in my trailer recently that straight up hate each other. Cussing and screaming and ready to go to blows, both were bigger than me and PISSED! Another super was in there when it started, he walked out and I saw him meet up with the PM, both knew what was going on and wandered off. I had to get louder and tell them how this was going to proceed, neither was happy because they both had to compromise. When it was over the job was running like a machine again and everyone was happy. Then the PM and other super came back in the trailer and it was my turn to go off! š¤¬
