Call centre giant Firstsource is cutting around 90 jobs in Belfast, it's understood.
The firm, which provides outsourcing for companies including Sky, employs around 1,500 people here.
But it's understood the Indian-owned business is now cutting around 90 staff in the next couple of weeks.
A spokesman for the firm said: "Firstsource is fully committed to the Northern Ireland marketplace and is continuing to invest in the region.
"As part of our long standing relationship with Sky, we have been working with them to maximise the customer experience we provide through our Service operation in Belfast. As a result, we are reducing the scale of operations in our Oyster House Centre and this will likely impact around 90 employees.
"We are actively exploring opportunities to redeploy affected employees across our other Northern Ireland centres, and are working to provide confirmation to those impacted as quickly as possible. We are committed to treating every employee with respect and are liaising closely with all affected employees to provide support and reassurance during this process.
"Our other operations in Northern Ireland are unaffected by this announcement. Northern Ireland continues to be a core part of our business - we have been operating successfully here for over 10 years and we remain as committed as ever to the region."
Firstsource employs over 27,000 employees worldwide, across 44 centres. More than 1,500 of its global workforce are based in Northern Ireland.
And just last month, Firstsource said it had reached a new 10-year customer service deal with Sky.
Firstsource will be providing broadband and TV customer service until 2026 after the media giant decided to consolidate its outsourcing deals with the company.
