The result of a ballot by RMT members over strike action in a pay dispute with COTA (Catering Offshore Trade Association) is expected today.
The union ballot results comes after Unite members voted last week on whether to strike after members of COTA went back on a pay increase which had been part of a two-year deal.
The result will be announced on the same day COTA chairman Peter Bruce said both sides would be going back to the table as they look to come to an agreement.
Earlier this month, 54.2% of Unite members voted for strike action while 62.7% voted for action short of a strike.
The body, which represents six catering companies working in the UKCS, has been in dispute with staff after it said it would not be honouring the second year of a pay deal worth around 1.3%.
The member companies of COTA are Entier, Sodexo, ESS, Aramark, FOSS & ESG and Trinity International Services.
