Regards the claim by the union that
We do not definitively know whether or not this wording was put forward by BA prior to or following the current dispute. As such, at this time the issue is not clear cut.
It's as easy as pie for any BA staff member to read the whole of the ST09 document on the intranet, each and every page of which states:
ST09 published by People Department and Staff Travel, 15th November 2007, Page 0 of 15
Staff travel is a non-contractual benefit granted at the sole discretion of British Airways and as such can be amended or withdrawn at any time
So, anyone from unite/bassa/cc89 reading this, there's your answer!
