Almost 1,000 jail guards were hospitalised in just one year, sending injury compensation levels to record highs.
Figures show 952 officers needed hospital treatment in 2021 for working in what one union boss has branded “the most hostile workplace in Western Europe”.
Prison Service data, revealed via a question made in parliament, shows the cost of compensation for staff hit a record £4.5million in the 12 months to April 2022.
