MORE than 200 workers at Imperial College London are set to down tools again on Wednesday as industrial action over pay stretches into its fifth month.

Technicians, maintenance workers, security staff and others are downing tools after bosses imposed a massively below-inflation 3.3 per cent wage deal, said Unite the union, which represents the workers.

The public research institution — which is “one of the best paying universities for senior leadership staff and has cash reserves of £1.7 billion,” according to Unite — was also hit by walkouts in November 2022 and January and February this year as the long-running dispute rumbles on.
