Management are employees too. One could argue that they are the normal employees, in that they are working for the benefit of the business, and strikers are abnormal in that they are damaging the business yet get to keep their jobs (if not their perks).

Striking for the good of the company seems a spurious defence for the blatant short-termism and self-interest exhibited by the strikers. One assumes that BA has departments full of highly-paid (and hopefully highly competent) accountants and business analysts working out exactly how to save money, manage their debt burden, and maintain good customer relations.

The cabin crew may be at the 'coal face' of customer relations, but there is no way they can see the the whole picture.
