Union representatives have met Wood Group to discuss the proposed changes to pay and conditions proposed by the company last month.
The company is seeking to cut wages and alter terms and conditions for Wood Group employees on Shell platforms in the North Sea.
The talks, which involved representatives from Unite and GMB, came a day after Wood Group PSN announced a three-year extension to their Shell contract securing 500 jobs.
Earlier this week, Wood Group announced it was consulting with 1,000 UK onshore staff as it planned to reduce headcount by 300.
John Boland of Unite said: “The unions (Unite and GMB) met today with Wood Group management to discuss their proposal for large scale redundancies, and to cut wages and terms and conditions on the Shell assets (Brent Alpha, Bravo, Charlie, Delta, Curlew, Gannet, Nelson and Shearwater).
“We made it very clear that this proposal was not acceptable to our members, and that if implemented would lead to a dispute situation.”
Earlier this week Unite Scotland accused the Aberdeen energy service giant of pushing North Sea workers to the verge of industrial action.
Tommy Campbell, a regional officer at Unite, said: “The morale is low amongst this workforce, as it is across the whole industry. Large oil operators are driving the cuts further and further. This is going to end up being a recipe for industrial action. It’s getting to the point where workers are saying enough is enough.”
