Members of trade union Unite working for IT services company Fujitsu have voted to accept proposals tabled by conciliation and arbitration service ACAS.
The proposals aim to resolve the dispute between Unite and the company over jobs, pay and pensions.
A four-to-one majority voted in favour of accepting the ACAS proposals following a 72% turnout. All industrial action will now be called off.
The dispute was over proposals for up to 1,200 redundancies in the UK, a pay freeze imposed last year and plans by the company to close the main final salary pension scheme to new members.
Fujitsu has cut the number of possible compulsory redundancies from 1,200 to fewer than 30 during the four-month dispute.
The company has extended the pensions contribution period until at least 5 March 2010 and offered a 5% increase in pay as compensation for changes to a defined contribution scheme.
Fujitsu has also made a "commitment to discuss more open pay and benefit scales as part of transparency talks" with Unite and recognised the union's aim to have minimum annual earnings of £13,500.
Peter Skyte, Unite national officer for the IT sector, said: "While the ACAS-brokered proposals do not fully satisfy our members' aspirations, there have been significant changes in the company's position on jobs, pay and pensions over the course of the dispute.
"Unite will continue to work with Fujitsu to avoid compulsory redundancies and press the company for a fairer and more open and transparent pay system that more adequately recognises and rewards the Fujitsu workforce for its contribution to the company's success and for improved pension provision."
