SCORES of non-medical support staff at Carlisle’s Cumberland Infirmary are to take strike action over a bitter pay dispute that been unresolved for more than a decade. Porters, cleaners, and switchboard staff say they have run out of patience with their employer, accusing the firm of denying them promised pay enhancements for the unsocial many routinely work. The public sector union Unison says that the workers involved were promised extra money for working nights and weekends more than a decade ago as part of an historic national NHS pay deal called Agenda for Change. It included ‘enhanced’ rates – such as time-and-a-half and double time – for working nights or weekends.
