I did also. I think it was from last Tuesday when the TSS at 130 Livingston came so we could sign in but then left because the orientation had already started. I remember he said he already knew who was there and would document us. I guess if they don't have our signature on the payroll sheet we do not get paid for that day. They weren't kidding when they told us every morning we come to work you say "good morning, where's the payroll sheet to sign in".
I will give a copy of my stub and location/times to my TSS on Monday and ask him what form we fill out to correct this. You can do the same. Your TSS can also let you know what to do.
