The Baillieu government has launched legal action against teachers' industrial action despite being in the middle of negotiations.

A spokesman for Finance Minister Robert Clark said proceedings had commenced in the Federal Court seeking an injunction against the proposed strike on 14 February and work bans that placed school camps, excursions, school fetes and sporting activities at risk.

The government will also seek a ruling that a range of items in the unions' log of claims cannot be included in an Enterprise Bargaining Agreement, thus rendering unlawful any industrial action in support of those claims.

The spokesman said the legal action followed the failure of the Australian Education Union and the Community and Public Sector Union to call off their industrial action despite being given ample warning of the government's intentions to issue legal proceedings.

"The Victorian government considers the proposed industrial action is unlawful under the Fair Work Act and would continue the AEU's unjustifiable disruption of children's education and the work arrangements of families and their employers," the spokesman said.
