I left TSA back in Feb, and the way it was explained to me, you will get one final check on the 15th. I also was a bit worried when I didn't recieve my 1st of the month check, but the deal is that they wait until the mid-month check, and pay you in one lump sum. Recall that your per diem and any hours over guarantee get paid on the 15th. Therefore you will get your final check then. Its just the way the payroll system is set up. You'll get your money on the 15th.
