Over 1,200 Unite union members will be starting a work to rule and overtime ban at the National Grid.
Members rejected a recent three year pay deal consisting of 2.5 percent, 2.25 percent and 2.25 percent rises.
National Grid then removed the three year deal at talks yesterday and offered a two year deal of 2.5 percent and 2.25 percent, which was also rejected.
