Reading between the lines here. The fact that the union are happy to be quoted. I'd imagine that this is a union led 'don't do any overtime this week' kind of thing. Putting pressure on the management to increase Sunday payments, and when they do they will all go back to work. Not exactly an organised walkout, but pretty much the same thing. Very sneaky.
This quote stinks of the union trying to put pressure on the managementThe Rail Maritime and Transport Union said workers were not taking organised action, but called on the firm to address staffing problems "as a matter of urgency".
I am also willing to bet that the guys who are out working today aren't in the union.
