Managers at BPM Media, publishers of the Birmingham Post and Mail, have been handed the document, which has been put together by National Union of Journalists members at the West Midlands titles.

The union says it is "extremely concerned" about the state of the business and does not believe enough is currently being done to promote the titles.

However despite the implicit criticism managing director John Griffith has welcomed the move, saying: "We do face real challenges as a business and welcome ideas from all of our staff."

Details of the plan are being kept confidential for commercial reasons, but issues covered include branding and attracting younger readers.

Chris Morley, NUJ organiser for the north of England and a former Post and Mail journalist, said: "The chapel is extremely concerned about the state of the business.

"Newspaper readers have to be worked for and that means putting real effort into winning their loyalty day in, day out. The journalists at BPM Media are anxious to do this and to show that they care about not just their own professionalism, but the well being of their titles as a business.

"It is vital that Trinity Mirror engages with its staff and that the company does not simply put this report aside to gather dust, but uses it to gather new readers and customers."

NUJ general secretary Jeremy Dear added: "Journalists want their papers and websites to be successful. They want to be proud of the role their titles play in the community. The Post and Mail chapel are showing management a positive future."

More than 70 editorial jobs were axed from the Trinity Mirror-owned titles last year.
