My lot keep telling me that working here is the best job they’ve ever had and we aren’t unionised, so it doesn’t mean that not being unionised means bad working conditions.
They are free to join a union, I think one is in a union. But it wouldn’t result in better conditions.
As for watching 70s newsreels about unions, well I remember the Dockers at Liverpool and the violence and intimidation is something I will always remember. Of course that doesn’t reflect all unions or arguably any union now, but I’d rather have stuck pins in my eyes than have joined one. Also, being a peculiarly independent git, I try not to join much at all.
