Left to the market, BA could easily get rid of the expensive pilot fraternity and replace them with cheaper contract employees.
Just like they could get rid of those troublesome catering contracters and nobody would notice the disruption at all. Evidently it has not occurred to Harry (clearly not a Harvard Business School graduate) that it takes rather a lot longer to replace nearly a thousand 777 pilots than 600 low paid catering workers. Given that BA employ almost one third of all UK ATPL holders and probably upwards of 75% of all 744 or 777 rated pilots in the country I'd be intrigued to see just who Harry thinks could bid for the work.
