Big labour has declared war on Stephen Harper and his governing Conservatives ahead of this fall's federal election.
The Public Service Alliance of Canada, the biggest of the 17 unions representing federal government employees, has vowed to "beat back" the Conservatives in October's vote.
PSAC is in the middle of a convention in Quebec City where 700 delegates are meeting to plot strategy in defeating their employer.
The main issue for PSAC is the plan to replace an unruly sick day system, complete with bankable sick days, with a short term disability system.
The plan, being spearheaded by cabinet minister Tony Clement, promises to reduce costs.
Currently federal public servants have 15 million banked sick days, the equivalent of more than 57,000 years of work.
The Ottawa Citizen reports that PSAC's executives are fuming over last week's budget where the Conservatives booked $900 million in savings on the expectation of changing the sick days system.
“It is time to get every PSAC member to vote to rid Canada of the Conservatives once and for all,” PSAC president Robyn Benson said in an opening speech to the delegates.
“Never has political action been more important. We’ve had enough of the attack on labour rights and on equality groups.”
PSAC, which in the past has endorsed candidates running for the separatist Bloc Quebecois but not the Conservatives, claims changes brought about by the Harper government are an attack on federal workers.
A recent study found federal workers earn more and work less than the private sector workers that pay their wages.
