In December, the print group proposed restructures within its web offset operations, putting around 150 jobs at risk across two of its businesses, Peterborough and East Anglia’s Heron.
A report from Unite said that redundancies had already started at the Peterborough plant, while Essex-based Wyndeham Heron is still in consultation over job cuts.
Falling demand within the magazine printing and web offset sectors was blamed for the cuts, as Wyndeham chief executive Paul Utting said that the latter market had declined by around 15-20% over two years.
He said at the time of the initial consultation that the shrinkage in the industry equated to around £50m in volume, enough to sink two factories.
Unite national officer Steve Sibbald said: "Unfortunately, Wyndeham Peterborough exclusively prints magazines and there has been a drop in demand, nationally and globally, for ‘ink and paper’ magazines because of the way news is delivered these days through the internet and mobile devices.
"Unite has and will continue to do all it can to support our members facing a bleak start to 2013."
He added that there was no similar work within a 50-mile radius of Peterborough, exacerbating the "terrible news" for staff.
