You're a temp, and they sent you a notice of termination letter? Lol. Good luck with that one. Here they just fire you.
We had a casual years ago that they loved. This was even before the hiring spree. Now they keep most off he street casuals that have a pulse. Anyway, they loved this driver. He was a LOCK to be put on permanent after Xmas. One night they send him a message asking him to cover a pickup. He was sick of having to do more work when he was done. Told them no. He got back to the building and they walked him off. Never to be seen again.
