Guy Smith, president of the 22,000-member union, says AUPE is filing another complaint with the Alberta Labour Relations Board.
The complaint suggests the government has conspired to undermine contract negotiations from the beginning.
Smith says his group also plans to file a charter challenge in Court of Queen's Bench and a complaint with the United Nations International Labour Organization.
This week, the government passed a bill revoking the union's right to binding arbitration and which imposes a four-year contract with a two-year wage freeze if the two sides can't reach a deal by the end of January.
Smith says that's akin to negotiating with — quote — "a gun on the table" and he won't do it.
