If BA have outsourced their IT to Indian companies then it is probably much like the situation at the large mobile telecoms companies in the UK which I have first hand knowledge of.
Management make a decision to outsource their IT function to a third party IT company based in India who provide staff to the UK office on UK work visas granted 'because they can't find the staff in the UK [prepared to work for the pay they are offering]'. It looks great on the bottom line but all the experienced staff are forced out - these are the people who have got everything running smoothly and reliably over years.
These Indian sourced staff are on wages of approx. one third of what IT consultants earn in the UK. They have little experience but are touted as experts yet are mostly fresh out of university in India without a clue how systems work. The telecom company is used as a training ground. The staff are rotated back to India every 6 months to satisfy and government visa restrictions and new graduates are sent it. They work very inefficiently preferring to do things by hand rather than automate them by writing programs to do the work quickly and reliably. That way these individuals become an 'island of information' and they can't be replaced.
Management actually gain security in their job by dumbing down the work force as the mess created by the outsourced company creates much, much management work for them.
So if someone needs to be fired at BA it is likely to be the senior I.T. management swiftly followed by the companies they outsourced to for putting in the cheapest people they could find.
