I was a full-time hub sup and I DID sleep over during peak. Slept on the couch in the training room. They had moved me to work in a building over an hour away from where I lived, and they wouldn't pay for my relo because the controller wouldn't approve it. So, after a 16-hour day, I couldn't spend an hour driving home, sleep for a few hours, catch a shower, and then drive another hour back to the building. Nothing aids in catching some ZZZs like the intercom going off every few minutes, or the sweet diesel fumes wafting up through the floor, or a member of the creepy cleaning staff waking me up to empty the trash...
There are things you could have done to prevent it. Next time, let your boss know that you are going to stay at the local hotel and put it on your expense account. Monday thru Thursday night. Tell them it beats paying the mileage rate. Do not let them put you in a position to work 16 hours a day. Come up with alternative solutions to cover the extra hours or inform them that the extra hours will be taken as time off when peak is over.
Part of the CA lawsuit was compensation or giving time off for hours worked for FT supvs. You will have to research it further if you want to know all the details.
Here is an effective way to handle a situation. When your boss or DM tells you that you are going to have to work an hour further away than you have been accustomed to, that is the time to work out an arrangement. Whether it is staying at a local motel or mileage or days off or a combination of those. Don't ever by "we don't do things like that". Arrangements are part of the culture...they are just not talked about.....like salary. Be discrete. Do not tell anybody about an arrangement that has been made. Leave that to your boss or DM.
Remember that solutions usually result or are influenced through a path of least resistance or what is quickest, easiest and least costly. It is human nature. A lot of the time a different and better solution will be brought to the table if they have to figure one out because of the "resistance".
Don't wait until you are already relocated to the new facility. If you are promised something and it is not delivered.... go to the next level and get HR involved.
Don't ever worry that your career will be derailed by standing up for what you believe. If you some reason you are black balled you have options. Also, I have seen entire Senior Staffs and District Managers replaced within 2 to 5 year periods. It usually only takes the one person to be replaced for you to get a clean slate back.
If you are diplomatic and respectful with a good sales pitch and confidence - you can usually get your point made without difficulty.
I can remember the District Manager telling me that I in two days I was going to have to go teach Manager Leadership School. I told him that no problem but UPS was going to have to pick up my tuition for my last class (I was taking) because I would have to with draw and forfeit what I paid in tuition. Gee - they found someone else to go spend 3 months away from home. That was only a $900 cost!
