Steve McGrath, chief executive of the MHS, said: “I am very pleased that the ballot was positive. The deal reached increases the flexibility available to MHS operational managers while ensuring MHS staff receive a fair wage for the work undertaken.
“Notice periods for changing work patterns have been shortened considerably and there will no longer be a right for staff in the future to receive contractual overtime.
“This is a fair deal for MHS staff, management, industry and the tax payer.
“We will of course continue to work with industry to identify and implement further efficiencies in the delivery of official controls.”
