We had one in BEA early 70s ..ex fleet air arm iirc..bit of a useless operator as when I first flew with him for three sectors wouldn’t let me touch anything. Come election time he was going to sort our pay out..had to do 2 years second officer, two years acting first officer before we got on the industry normal salary scale. Negotiated nothing for our group then resigned and became deputy flight manager. Was sent to Coventry by one and all. Had a couple of good reps after him.
Seem to remember that the guy who ran BA came from AERLINGUS pilot’s union.
