"The CPI(ML) Red Star has called on all party committees to mobilise militant, vigorous campaign utilising all mass organisations and democratic forces in support of the strike," party general secretary K N Ramchandran said in a statement.
The party accused the NDA Government of following neo-liberal economic policies 'aggressively'.
Central trade unions had in May this year called for the September strike accusing Government of diluting labour laws suiting the needs of corporate houses.
