Regarding these comments then the BA walkout a few weeks ago starts to make more sence as does the idea of BA annualising hours.
One thing though I cannot see any airports / airlines or GHA wanting to take more staff even at a reduced rate of pay. That and the criminal records check should lead to more vacancies but recruitment costs a fortune and often if you process 100 you lucky if you get 7 or 8 staff with no garantee they will remain.
