All workers should have the "right" to protect there working conditions and have a descent working wage- simple as.
Again... do you have any idea what part of the RM workers' pay and conditions isn't decent? Because I certainly can't see it, and it seems that most RM staff don't see it either. At my wife's delivery office there are precisely zero staff striking... they are reasonably paid for what they do and about the only part of their conditions that I see as even slightly draconian is the handling of time off sick.
Still, the unions and their more vocal members are managing to reduce any miniscule amount of public support they might have had and are making themselves look like fools (since they don't seem to be fighting any particular point of common contention, and a large number of staff (including union members) are carrying on regardless.) The sooner they leave and provide a job opportunity for someone of a more suitable disposition the better - if they're really so hard done by they should easily find a more cushy job elsewhere.
I work for myself; if I don't get just on with it I don't have any income. I get almost no holidays (never a complete uninterrupted week off, and definitely less than a fortnight in the year) - we would all like better holidays, more pay, less stress etc but I'm grateful enough to be able to pay my own bills without sponging off the state... if I don't do my job, there will certainly be a competitor spring up to do it instead.
