A total of 310 jobs are to be lost following announcements by separate companies in Cork and Sligo.
Option Wireless is to cut 150 jobs at its plant in Cork as part of a cost-cutting plan by its Belgium-based parent company.
Option Wireless, which makes wireless communications products, said the facility at the Kilbarry Industrial Estate would retain 22 people.
The Cork plant has been responsible for customising the company's products, mainly by adding software. Its activities are to be transferred to what the company called 'lower cost' regions in Asia.
Option said the first lay-offs were likely to take place in January next year, with further redundancies at the end of March.
Elsewhere, 160 jobs are to be lost at a call centre in Sligo. The Tiscali contact centre in the Finisklin Business Centre is to close down in six months time.
Tiscali is part of the Talk Talk group, a UK supplier of phone and broadband services.
Talk Talk took over the Sligo business in June of this year and says that following an extensive review it is going to close the facility.
Talk Talk issued a statement saying that: ‘As processes improve and fewer customers call us, we have taken the decision to so consolidate and create Centres of Excellence enabling us to serve our customers better.
‘The result is that work currently undertaken in Sligo will be moved to other locations including Waterford’.
The call centre in Sligo first opened in 2006 when it was operated by a company called Toucan which promised 300 jobs.
