Most strike votes on the railway are not about pay, despite what the newspapers might state, but about the eroding of conditions linked to the offered pay-rise.
The "Railworkers strike because 5% pay rise is not enough" usually means "Railworkers offered 5% payrise if they give up signing on time, walking time and holiday pay strike to protect their conditions" doesnt have the same ring to it!
Both headlines are factual, its just that one is more factual than the other.
I think between 2009 and the current day a lot of people would be very happy to get a pay rise even if it involved less favourable conditions e.g. shorter lunch break, start a bit earlier or finish later, charges being introduced for parking permits etc. Of course they'd prefer the pay rise without the extra conditions but unless you're promoted or take on extra responsibilities such pay rises are infrequent and usually very small increases.
If you recall the last Northern strike that related to benefits that had already been surrendered.
The union previously accepted that the contracts would allow 2 bank holidays (Christmas and Boxing Day) off work not 8. However, when Christmas and Boxing Day fell on a Saturday and Sunday respectively the usual Bank Holiday lieu days were given by the government on the 27th and 28th and the union claimed Northern employees were entitled to all of the 25th, 26th, 27th and 28th December off work.
While a ballot was called a lot of members didn't actually vote even though a strike was called and numerous Northern employees said at that time they weren't really bothered about what was happening with regards to working on 27th and 28th December. However, they did want clarity on what would happen when for the genuine additional bank holidays which were upcoming for the Royal Wedding and Queen's Jubilee, which they hadn't yet been given.
