Eight camera operator and video editor posts face redundancy in UTV in Belfast.
The broadcaster's resources department, which currently employs 16, is being targeted in the latest cutbacks.
The department is to be restructured and staff asked to re-apply for eight posts. Trade union Bectu said: "We are waiting for the company to commence consultation and until they do so there will be no redundancies.
"So far, the company has declined to respond to a request to consult."
Compulsory redundancies this summer hit the roles of head of news and head of resources leading to the exits from Havelock House of ex-News Letter editor Darwin Templeton and former BBC Scotland man, Brendan Mallon.
A spokesman for the plc, which is the Channel 3 licensee in Northern Ireland and also owns 21 radio stations, said: "UTV does not comment on staff matters".
UTV is one of Northern Ireland's few listed companies.
It has been under increasing pressure because of falling advertising revenues.
The company reported a 43% decline in pre-tax profits to £6.1m in the six months to the end of June.
