Interesting. We just started a 1-5 pm sort in my hub. It started this past Monday, and they had us come in at 12pm, and work to 5pm. They then made us clock out, and then clock back in at 6pm, and work till 10 pm (which is the normal twilight shift). I was told by the management team that there would not be overtime paid, which is why they broke it up into two seperate shifts. They also said after cyber Monday, there would be plenty of overtime available.
