GMB Scotland members at a huge Ministry of Defence (MoD) munitions depot are voting on industrial action.

Workers at the 180-acre site at Beith, which is managed by Defence Equipment and Support (DE&S), have accused management of disrespect in a row over bonus payments.

Non-craft workers at DM Beith, in North Ayrshire, who prepare arms and munitions for transport, are being balloted on potential strike action after being refused the same retention bonuses as managers and craft workers, who assemble the munitions for UK armed forces.

GMB Scotland says the decision to limit the extra payments, intended to reward staff working through particularly busy periods, to only some workers has created division and ill-will at the depot and us urging management to act with urgency to ensure workers are treated equally.

Chris Kennedy, GMB Scotland organiser, said: "It is disheartening to see such blatant disregard for the principles of fairness and respect in a modern workplace.

“Non-craft workers are integral to the smooth functioning of DE&S and their vital work deserves the same reward and recognition as their colleagues.

“Managers are effectively telling non-craft workers their efforts are not valued and unappreciated. It is unfair, discriminatory and will not stand.

“Our members are being balloted on industrial action and we would call on DE&S to address this issue with urgency and commitment.”

While it is understood that DE&S continue to engage with its trade unions in working towards reaching a satisfactory resolution for all parties.

However plans are in place should action take place.

An MoD spokesperson said: “We are aware that GMB members are being balloted on strike action at DM Beith.

"In the event of industrial action, pre-planned contingency measures would be implemented to ensure the continued operation of the site.”
