Furious workers at a Basingstoke printing firm held a four-hour walkout on Wednesday last week.
Wyndeham Impact on West Ham industrial estate is due to close, with the loss of 58 jobs.
Employees at the firm have accepted the closure, but are angry over what they claim are broken promises relating to pay.
Last week, they launched a series of two-hour daily stoppages following weekly four-hour protests earlier this year.
The strikers were calling on the company to honour an agreement to reimburse a voluntary pay cut taken two years ago.
According to workers’ union Unite, staff took an 18 per cent pay reduction in April 2009 to help keep the company afloat during the economic crisis.
The protesters said the company had performed a U-turn on its promise to repay the cash.
Unite assistant general secretary Tony Burke said: “These workers, who have made a massive sacrifice in their pay to support the company, feel totally let down by the management. We urge the management to do the right thing and honour their commitments.”
Justin Fleming, 37, from Basingstoke, who has worked for the company for 10 years, said: “Two years ago, we took a pay cut – they said the site would close without it.
“They also said we would get everything back in a year and a bit on top. But two years later, we have seen nothing.”
Unite national officer Steve Sibbald said: “Our members took a 13 per cent pay cut over a year ago to help the company during a very difficult financial period.
“They now feel betrayed as they feel that this gesture of good will has done nothing to help their cause, but feel it has instead bolstered the company’s profits.”
In a statement, the company’s chief operating officer, Roy Kingston, said the company remains in financial trouble.
“After reviewing Wyndeham Impact’s financial performance, along with other principal factors such as the requirements of our customers, our manufacturing capacities and the cost of production, it shows that the business is not sustainable as a stand-alone entity,” he said.
“We have reviewed a range of options to find an economic solution that would make the company viable. So far, we have been unable to find a workable business model.”
