Sir Keir Starmer is facing a growing wave of industrial action despite earlier efforts to appease unions with nearly £10billion in public sector pay rises.
Teachers, NHS workers, civil servants and university staff are all threatening strikes over pay, job cuts and working conditions in the coming months.
The fresh wave of industrial action threatens to cause chaos in streets, schools and hospitals across the UK this spring and summer.

The Government has called in the Army in an attempt to bring the Birmingham crisis closer to an end.
The National Education Union also announced on Tuesday it would launch a formal ballot on industrial action if ministers' offer "remains unacceptable".

Andrew Griffith, the Shadow Business Secretary, said ministers were "reaping what they sow" with the industrial unrest.
