I wouldn't pay too much attention to that 'letter' if it's anything like the diatribe that unite sent out to all the other members who are in engineering. After all its a union for engineering that glibly goes on about 'ageing and ill maintained aircraft', about recruiting engineers for a more professional body (the ALAE) and warnings about not copying in senior managers in emails of complaint.
I am still waiting for my "letter" courtesy of the Post Office, but it seems Unite is spreading it's bullying and threats to Engineers as well. That will get short shrift for sure!
Anyway, who the F*** do they think they are.
