Unions will be urged to organise national days of protest and co-ordinated industrial action against the Government's public spending cuts during the TUC's annual conference next month.
A motion tabled by the Rail Maritime and Transport union calls for an immediate summit of union leaders to discuss how to co-ordinate industrial action to defend jobs, services and pensions.
The union will also urge delegates at the Manchester conference to set up an alliance with users of public services as well as national days of protest and a lobby of Parliament.
RMT general secretary Bob Crow said: "The TUC has to be the launch-pad for the fightback against the coalition Government's decision to launch all-out class warfare through their unprecedented attack on our communities, public services, welfare state and transport system.
"Our defence must be built on generalised strike action and community resistance in the biggest public mobilisation since the anti-poll tax movement.
"RMT is in no doubt that the Government is using the deficit as a thinly veiled cover to engage in an ideological dismantling of the state and an attack on workers, and the most vulnerable in our society, which goes far further than even the dark days of Thatcher."
The TUC Congress is being held from September 13 to 16, with the public spending cuts expected to feature heavily in debates.
No Government ministers will address the conference but speakers will include Bank of England Governor Mervyn King.
