Around 120 protestors are expected to gather outside Pinderfields Hospital today to burn their redundancy notices.
The five-day strike of Admin and Clerical staff at Mid Yorkshire Hospitals NHS Trust, which began on Monday, is part of an ongoing row over pay cuts and contracts.
Members of Unison working at Dewsbury Hospital, Pinderfields and Pontefract General Infirmary face pay cuts of up to £2,800 a year, the union claims.
The Trust says it needs to identify savings of £24m by April.In November, Unison members at the three hospitals held four days of industrial action against the proposals.
In the same month, the trust sent redundancy letters to 74 members of clerical and admin staff.
It then began to distribute dismissal and reengagement letters to up to 300 staff. The letters contain the new contracts on lower pay bands.
Tomorrow, at 1pm, hundreds of strikers will meet in Wakefield Town Hall for a rally.
