Windytoo, having just joined BA from a UK charter airline where I often had the chance to fly a visual approach to a Greek island in the middle of the night could I point out that it is BA and not the BACC who have decided that Openskies pilots are not the same as BA pilots, indeed under the current proposals if an Openskies pilot wishes to join BA they must go through the same selection process as a candidate from any another airline. If the BACC's proposal was accepted Openskies pilots would be able to bid for another fleet with no restrictions.
If you think that BA T&Cs are rooted in the 1930s then you are delusional. When I worked for a charter airline that flew to Greek Islands (and much longer sectors) I worked less overall for more-or-less the same money. Incidentally the company I used to work for used BA amongst others as a benchmark for the last pay deal I voted for which increased salaries for some by as much as 10-15% so from my experience it is your assertion that is "complete tosh"
