Three photographers are among eight editorial staff at risk of redundancy at two sister dailies, according to the National Union of Journalists.
Among the new roles are three digital sports writers, a city beat reporter and a breaking news blogger.
TM has declined to reveal which posts are set to go, but the union claims they include three of the MEN’s eight-strong team of photographers, and the head of news at the Examiner.
A Trinity Mirror spokeswoman said: “MEN Media is introducing six new digital content specialist roles – five in Manchester and one in Huddersfield.
“To allow for creation of these roles, several existing roles are at risk and we have entered a period of consultation with all directly-affected staff.”
Five of the new roles are being created at the MEN and one at the Examiner.
The new MEN roles also include a “trend writer” whose job will be to focus on content which is trending on the internet and create “compelling local stories” around this.
According to the union, the four MEN roles due to be axed nclude three photographer posts and an assistant publishing editor.
At the Examiner, the roles understood to be at risk include two part-time admin staff and a community content curator as well as the head of news.
A fortnight ago, Trinity Mirror announced similar restructures at its Birmingham, Liverpool and North Wales centres, with 18 jobs at risk and 16 new roles to be created across the three areas.
At the same time, TM also revealed plans to axe the equivalent of 13.5 full-time posts at the recently-acquired former Local World weeklies in Essex, Kent and Surrey.
Chris Morley, NUJ Northern & Midlands organiser, said: “Once again news photographers are in the line of fire with media companies in the grip of an obsession that quality news images spring from nowhere or can be plucked relentlessly with no cost or worry from the internet.
“This is a false and damaging belief and such cuts are proving elsewhere to be cuts too far.
“The NUJ welcomes investments in digital journalist jobs. But the central and compelling question about a sustainable digital strategy that will pay for quality journalism still remains.
“Our members quite rightly want to see hard evidence of this before more resources are taken from elsewhere.
“We ask that Trinity Mirror be much more open about its plans for digital transformation, which it says are local initiatives, but are clearly being driven by a central strategy to its regional centres.
“Answer the questions about sustainable levels of digital income and sustaining a real quality of journalism online, and NUJ members would be a lot more understanding of these changes.”
