Workers at an engineering plant in Fife are preparing for a two-day strike in a row over redundancy payments.

US firm Oceaneering announced in July that it was planning to make 120 of its 210-strong workforce at its Rosyth base redundant.

Unite the union claims the firm has now backtracked on previous agreements after offering to pay the "legal minimum" in redundancy pay.

Representatives say the move is a "slap in the face" as Oceaneering, which predominantly serves the offshore oil and gas industry, "continues to make big profits".

Rosyth-based Unite members started a continuous overtime ban on Friday, followed by a 48-hour strike from Tuesday.

Unite regional officer Ian Ewing said: "We remain in consultation with the company to try to save as many workers as we can from compulsory redundancy.

"We have continued to raise the issue of redundancy pay and our message is quite clear - our members have worked their socks off to deliver for this company and they should be treated with fairness and respect.

"For the company to then declare over half of their workforce at risk of redundancy and to say that they intend to only pay statutory redundancy is a slap in the face."

Mr Ewing said when Oceaneering went through previous redundancy rounds in 2008, 2009 and 2013, the company agreed with the union that workers would receive enhanced payments of at least double the legal minimum.

The Houston-based firm was not available for comment on Friday but a spokesman previously said the business was struggling with a "significant slowdown in deepwater activity attributable to the harsh decline in crude oil prices".

He added: "Oceaneering finds it necessary to adjust the company's cost structure by reducing some staff at our Rosyth facility as we align our capacity with current market demand.

"Managing this process with the utmost consideration for our staff will be a top priority."
