Well that is one way of looking at it
PR. If all employers were reasonable, we would not have unions now. As I have said before, we are only 100 years past the master and servants act. The law says to collectively negotiate, you need to be collectively recognised. Collective bargaining makes sense when you have the employee structure that BA have in cabin crew. Three roles and 12000 employees. When it works it is simple and the reps get the stick.
