Workers at a Rochdale manufacturing site will walk out again in January after union leaders accused management of unfair dismissal, unlawful strike-breaking, and refusing to negotiate.

The dispute involves Tetrosyl and its distribution arm, Tetrosyl Express, where staff have taken multiple days of strike action in December over the company's use of so-called ‘fire and rehire’ tactics. Usdaw, the union representing the workers, claims the new contracts would see employees lose between £4,000 and £7,000 a year, with some couples facing household losses of up to £14,000.

A further strike has now been called for Friday 2 January, running from 6am to 9.59pm, after management allegedly escalated matters by dismissing a worker and bringing in agency staff to undermine the industrial action.

Usdaw says the use of agency workers, reportedly supplied by Ideal Recruitment, is unlawful under current strike regulations. The company also stands accused of failing to recognise the union or take part in negotiations.

Michelle Byrne, area organiser for Usdaw, said: “Tetrosyl management are behaving appallingly in this dispute and they are, like the Grinch, trying to steal Christmas from their staff.”

She continued: “Rather than reasonably seeking a resolution, the company is illegally bringing in agency workers and forcing us down a legal route to secure recognition. One of our members has been unfairly dismissed, which is devastating for them and their family at this time of year.”

Usdaw says its members voted overwhelmingly for strike action, with previous stoppages taking place on 15, 17, 19 and 22 December.

The union says the new contracts strip out paid breaks and shift premiums, reducing wages to near minimum wage levels. It has condemned the employer’s approach as “immoral”, particularly in light of Tetrosyl’s reported £2 million dividend payment to shareholders last year.

“Rather than slashing terms and conditions, they should take on board the strength of feeling among their workforce. These workers have helped build the success of the business and deserve better,” Byrne added.

The union says it remains open to talks and has urged the company to return to the table.
