Swindon hospital workers announce strike dates
Porters, cleaners and domestic staff at Swindon's Great Western Hospital are to hold three one-day strikes.
The GMB union, which represents 150 of contractor Carillion's 200-strong workforce, said 97.3% of voters backed the action over "bullying".
The union said it also wanted a fairer holiday system for workers while Carillion said it was "very disappointed" at the action.
The strikes will be on 14, 21 and 23 February.
Carillion said there is "robust contingency plans in place" and that they would ensure "patient care is not compromised".
