If you screw up on stupid basic common sense stuff, no, you'll at very least get bitched out. Usually, so long as you're not affecting productivity in a bad way, not creating bad relations, being reasonable and cooperative, you're fine. The worst that happens is when you have a supervisor or a foreman who brings along his home town buddies who are unqualified for the job and he ends up coddling them or letting them get away with bad behavior or poor standards. In that case I keep my head down and try to stay out of conflicts because no matter what, I'm gonna be the one to get blamed. On one crew the foreman had his son in law, a friend of his son in law, a nephew and his wife on the crew plus some others who were hangers on or something. Three of us were tasked with welding out some floating pontoons and I followed standard procedures and welding sequence. They tested out the pontoons after we had already gone on to another project and my foreman got notice that there were just a huge amount of leaking welds. I got blamed and was sent back to repair the leaks. Just hearing that they thought it was my fault sort of peeved me but then, I'm not infallible so I left without protest. After all, I get paid for miles I drive and I like driving anyway. I got to the job site and started going into all three pontoons where I had welded. I only found three tiny leaks which is normal and had them sealed in a few minutes. However, going into the other pontoons I discovered they'd been welded out of sequence, poor technique and a huge amount of leaks occurring in every corner and everywhere there was a joining of welds. Too cold weld, cold lap is the term used, poor connections and wrong sequence. Just basic stuff but I fixed it all that day and went back to the other site to rejoin the crew. If I had said anything there would have been denials and counter accusations so I said nothing. Every job I was on with that crew stuff like that happened. When two of the foreman's relatives were separated from him and sent to a project where he had no control they got fired in short order as they should have been. They were constantly messing stuff up, bloviating about how great they were all the time big daddy covered for them. At NASSCO shipyard it was always production, production and production that counted but the crews got into a habit of passing the buck on fixing defects and laying it all on the third shift to cover for them. I eventually got tired of it, of the lying and shifting labor to us so I put in some really hard hitting reports to get all that ground to a stop and had some frank discussions with my foreman and supervisor about rules being skirted. Rules clearly spelled out in literature that we had in our hands daily. To their credit, I was able to reason with them about how this was not only going to cause us to lose the crew and be split up but both the foreman and supervisor would end up losing their position and be placed back on their tools to work with us. In like one week of carefully placing unsaid threats in the minds of those on first shift by subtle hints and revelations about what I knew plus the reports I was making sure got to the front office all the scheming and back stabbing just stopped cold. In the right situation with the right people one man can indeed have a huge effect on even a business that employs thousands. You just have to work carefully with the system. Some crews though, are just doomed right out the gate with poor leadership and cronyism that brings in trashy workers. One project I was sent to on an emergency basis was because the previous crew who were all friends and family were completely unqualified. Thankfully I had no part in what went on or I would have lost my mind. They would work a couple hours then take off for the day and record it as a whole day worked. They were way behind because of the fraud on hours worked. The welding they did do was horrible and had to all be redone. It's actually fortunate they got fired after "finishing" one tank which we had to go rework to pass inspection on it. I think on that job the company actually broke even.
