Fujitsu has increased its UK-wide minimum wage by £2,000 to £14,000 for all staff.
The company first set a £12,000 minimum wage in 2010 as part of an agreement with trade union Unite, with a view to review the level each year.
Unite has been asking for an increase to £15,000, and where Unite has collective bargaining, Fujitsu has agreed to an increase of the minimum wage to £14,500.
"With pay awards recently agreed, that is expected to take all employees to over £15,000 per annum," Unite said.
In this year’s pay review, Fujitsu decided to give lower paid workers a higher percentage increase, so that monetary rises were nearly as much as those for those on higher wages.
Kevin O’Gallagher, Unite national officer for IT and communications, said: "Members welcome a fairer approach to pay from Fujitsu this year, which will mean many employees receive bigger rises than they have done for years.
“However, the company has made clear that it sees the 2012 pay review as a ‘one-off’, so it will be important for staff to continue campaigning to ensure Fujitsu establishes a fair and transparent approach to pay and benefits.
"We are calling on Fujitsu to sign up to the Fair Pay charter for the IT services industry," he added.
