Just to clarify, the info posted by PC767 is an email from the A Scale NSP to groundstaff such as Check-In etc. It was sent out last night.
I guess BASSA may also have seen the found document, but as far as I am aware (as a BASSA member), it has not yet been circulated to us.
It was released to BASSA members on their forum this morning (as disclosed here) but the BASSA reps have had the full agreement since Monday 15th June, courtesy of the BALPA reps.
As we know from the Open Skies court case, emails and phone calls are a matter of record and can be used as evidence. Dodgy legal ground if you want to try to call a strike ballot.
