I did what they told me to do. The agency that handled this particular location was way more disorganized than the other one, where no such thing took place. It gets more complicated. At this location, I showed up twice and was sent home because they reached the capacity of people that they needed, and didn't email or call me ahead of time to tell me not to come before I got there. I argued with them about how they should've told me before I drove out there, and that driving took two hours to get there and two hours to get back home. The sign-in ladies both told me that I could add a few extra hours to my online timesheet for those days, their exact words were "as a courtesy" for having to drive out there and be sent home. They didn't let me put those hours on the physical sheet though, but they insisted that I could do it on the online one. The payroll lady said that one of those ladies was working there for 20 years and would never tell me to "falsify documents", but she and the younger lady working with her both did.I have ZERO doubt that falsifying your time sheet at one location is going to make it difficult for you to prove your case that they are somehow the ones who can't be trusted.
The other location was way more organized, they had two sign-in sheets, one at the entrance handled by a guard, and one in the room where we all sat and waited to be called upon. My physical and online timesheets for that location match each other, but they removed an entire week that I worked and won't pay me for it, and I have video evidence that proves I was there on the graveyard shift day that they claim I wasn't there on.
