UNISON members will form a picket line at Causeway Hospital this Friday during a day of action across Northern Ireland.
The protest has come as a result of damaging cuts imposed on public services by the government in the Stormont House Agreement.
A UNISON march will be held on Friday, March 13 from 2pm from Causeway Hospital to Coleraine Town Hall. Union members will be picketing from Thursday.
UNISON is calling on all local communities across Northern Ireland to support this strike to save their public services, a spokesman said.
