Yeah idk but the union needs to take a look into it for sure. Kind of seems like a step backwards - especially if you read the language in the FIL that MK sent. A lot of things in that verbiage can be used against you. Basically when you are checking that check- in box you are agreeing to a lot of things.
Also, check-in just became a 2 step process instead of a 1 step process. They literally made it more complicated instead of easier. Typical PDT.
