Future recruitment and transfers into LHR won't be on the EXCISTING contracts. At least that is how I interpreted the email which was sent out tonight. So, they want to get rid of the present T&C and eventually get rid of them. Future aircraft coming to LHR would also most likely be crewed by those crews. Sooner or later present crew would need to transfer because of lack of work.
I don't like the idea of going on a strike at all! I think it will really place us in an awful situation.
