Unite has ended its long-running industrial dispute with Fujitsu, which centred on pensions, pay, overtime and other issues at the IT services provider.
On Friday, the union signed a new agreement that raises pay and provides an 'escalation' method for employees wishing to express concerns to upper management.
The industrial action in the dispute had been suspended in late 2011 and, with the signing of the agreement, the grievances have been partially resolved.
"The agreement reflects a significant improvement in relationships with the company since last year, it means better protection for pensions for Fujitsu employees across the UK and pay rises for most Manchester staff," Kevin O'Gallagher, the Unite national officer for IT and communications, said. "There is a renewed commitment to work together through our agreements which can help avoid conflict in future."
Unite had been at loggerheads with Fujitsu over the treatment of workers at sites in Crewe and Manchester. In September Unite members went on strike in Manchester, leaving at least one datacentre "essentially unmanned".
The deal means Fujitsu will not punish employees for participating in industrial action or campaigning; will grant small pay increases to Manchester staff, backdated to 1 August 2011; will publish a statement on the contractual status of Fujitsu employees' pensions; and will establish an 'escalation route' by which employees can raise concerns.
Unite representatives in Crewe are organising a meeting to discuss the agreement.
