When management knows air will be late they come around and ask if anyone on the preload is willing to stay buts we have to punch out and wait until the air arrives and then punch back in. Then when all the preloaders refuse they claim it is an "emergency" situation and management sorts and shuttles air out. I was off my 2nd job today so I decided to stay. I told the center manager that when I worked in Ohio before my transfer we never were made to punch out. I asked him if I punched back in then I should be guaranteed another 3.5 hours and he just laughed....called it "supplemental" work! So I at least witnessed 3 of the managers working to catch everything off the belt since this time since we still did not have enough people. How does this work in your buildings?
