Talks will take place this week in a bid to save jobs at Tayport textiles firm Scott and Fyfe.
It is understood there will be redundancies at the Fife company, which employs around 80 people manufacturing technical textiles for a range of industries.
David Lawson, regional officer for the Unite trade union, said he could not speculate on the number of jobs at risk until after a meeting with management on Thursday morning.
“We want to get to the truth of what’s happening, instead of rumours,” he said.
“We want to know in detail what’s happening. We’ve got to think about the workforce, who might not know exactly what’s going on yet.”
The Dundee area has recently been hit with devastating mass redundancies, notably Michelin and McGill.
“We know the blows that have been taken in this area and we have to stop that,” said Mr Lawson.

“I’m going to do everything in my power to try to save jobs.
“We’re trying to save as many jobs as we can. If we can’t do that Unite will fully support members going through the consultation period.”
Initially started as a linen works in 1864, Scott and Fyfe now supplies industries across the globe with technical textiles. Its products are used in sectors including construction, medical, sports, aerospace and energy.
Last year, Scott and Fyfe chairman John Lupton said he was optimistic about the company’s future after it returned to profit.
It had plunged into the red in 2015, when the firm reported a £838,000 loss from sales of £11.51 million.
The following year, it had a pre-tax loss of £391,000 due to losing a major customer.
However, the employee-owned company recorded a pre-tax profit of £32,000 for the year to December in 2017.
At the time, Mr Lupton, who took over as chairman in 2017, said trading conditions within the flooring division were “tough” as customers moved to buying lower specification products.
In response, the company launched new flooring products at the start of last year and also added new products in its pipe fabric division.
