I get that you're mad at unions, but labour negotiation isn't simple. The Miller administration tried to eliminate the sick bank for public workers, and ended up with a forty day strike that cost him a ton of popularity and contributed to his desire to leave politics.
Just because Rob Ford is also angry at unions doesn't mean he's going to be able to magically rein in labour costs. In fact, without a coordinated strategy and any attempt to build positive relationships with the union heads, he's likely to just make the situation worse. He's already handed the police union their largest pay increase in years and is set to do the same thing with the TTC in the months ahead, thanks to his short-sighted desire to designate transit an essential service.
And 'the left' certainly isn't synonymous with 'unions.'
