A northern NHS Trust is attempting to sack 5,000 workers and re-employ them on worse terms and conditions.
Unions today staged a protest at North Tees and Hartlepool NHS foundation trust's board.
The GMB union said the trust wants to axe enhancements which recognise unsocial hours such as nights and weekends if they are on sick.
Regional organiser Keir Howe condemned the "appalling" act that he said would cause the workers to lose pay, reduce their pensions and maternity pay and discriminate against the disabled.
He said this was an issue across the NHS but, instead of waiting on continuing talks, the trust had just pushed ahead.
