In June 2022, Kwarteng vowed to shortly press by adjustments, “repealing these Nineteen Seventies-era restrictions” to provide “companies freedom to entry totally expert employees at velocity”. The then transport secretary Grant Shapps stated it was a “important” reform to minimise strike disruption.

“There’s a cause that employees select to strike – and it’s not at all times nearly pay. Many are vastly involved about working situations. By permitting temps to switch them in these similar situations, the federal government was displaying zero consideration for the welfare of non permanent staff.

“With this ill-thought-out laws thrown out, the main target should flip to the fairly frankly immoral anti-strikes invoice. The earlier that is torn up too, the higher.”
