Up to eight jobs are under threat as part of a restructure affecting around 14 weekly newspapers.
Johnston Press has announced the move which will see its Northern Ireland weeklies published to strict templates under the same basic 48-page format.
It is understood affected staff have been told they can apply for voluntary redundancy or reduced working hours, with eight full-time equivalent positions at risk.
Weekly titles run by JP in Northern Ireland include the Ballymena Times, Ballymoney and Moyle Times, Banbridge Leader, Belfast News, Carrick Times, Coleraine Times, Mid-Ulster Mail, Tyrone Times, Newtownabbey Times, Larne Times, Lisburn Echo, Ulster Star, Londonderry Sentinel and Lurgan Mail.
Belfast daily The News Letter and the bi-weekly Derry Journal are thought to be largely unaffected by the changes, as are JP’s central digital and sport teams for Northern Ireland.
Last month the company announced changes to the editorial structure of its 28 Scottish weekly newspapers, with the National Union of Journalists estimating that up to 25 editorial posts were at risk as a result.
JP said the move had been decided as a result of “challenges” faced by readers accessing news online and “industry giants” such as Google and Facebook changing the way people read news.
Jeremy Clifford, editor in chief of Johnston Press, said: “We have announced we are looking for a number of voluntary redundancies as we continue to find ways of ensuring our titles remain profitable and face the challenges in the industry. The News Letter is unaffected by the changes.”
