Exactly Devil.
It shouldn't be about "them" vs "us" or "have" vs "have not". Bringing everyone down to the lowest level just makes everyone worse off. Redundancies, pay cuts, reduction of T&Cs, etc in any employment sector impact on the economy as a whole because it has a knock-on effect. Pay me less and I'll spend less at the shops, I'll cut back on luxury items like Sky or take-aways or trips to the local pub, cut my hours and I don't need to use the car as much to commute so I'll buy less petrol or I'll use the bus less because I'm not commuting as much. Then multiply that reduced consumer spending by thousands or hundreds of thousands. Then factor in the benefits unemployed workers will need to claim or the top-ups workers on reduced incomes will need to claim to sustain them (e.g., tax credits, etc). How does that aid the economy?
We should all be standing up and fighting to raise standards to those of the highest level, rather than dragging then down to the lowest. Public sector workers didn't cause the financial problems, they're victims of it just like everyone else. When times were good and business was booming, they got nothing extra yet when times are bad they're demonised as leeches sucking funds from honest taxpayers and doing very little to earn their keep.
Our strikes and contractual disputes get a lot of press because our unions are some of the few unions still actively fighting these issues. We've already made cut backs and savings, I could go into it but wouldn't want to be seen as "bleating" however large parts of the public sector are struggling to deliver services with barely any resources, reduced staff numbers, and a lack of equipment. The same people who bemoan us using up valuable taxpayer funds and cry for cut backs are then the same people who complain about waiting lists, call queues, and processing delays.
I still say YABU, there is more to the public sector than you realise or give credit for.
