Couldn't agree more.
I NEVER ack'n a roster change, ever, and rarely ever get mucked around.
3 times I have shown uP at Kitty City (knowing I wouldn't be flying it) but my official duty was as rostered, so off I go.
Get sent home an hour later, no more work.
CC must have a system that "grades" people on their amount of ack'n.
No wonder I don't get stuffed around, coz I DONT F&@KIN' ACK.
Put 2 n 2 together....
