Up to 19 jobs are set to go as two Johnston Press-owned dailies in Yorkshire merge their editorial teams.
Now the two Leeds-based titles are proposing to combine their entire newsrooms with the loss of 19 jobs overall.
Nine voluntary redundancies have already been accepted and a further ten are being sought with a sports editor role and the post of YEP business editor among those under threat.
Among those leaving the YP are the associate features editor, chief content editor, senior content editor and rural affairs correspondent.
YEP staff departing include the news editor, deputy news editor, crime correspondent and sports content editor.
Other roles at risk of redundancy include those of Halifax reporter YP, features content editor YEP, head of digital operations, chief designer, a sports journalist role and three secretarial roles.
An internal memo circulated to staff this week said the changes would address the duplication of roles and achieve greater efficiencies, while maintaining a differentiation between the two titles.
Johnston Press chief operating officer Danny Cammiade said in a statement: “Following a strategic review of the Yorkshire Evening Post and Yorkshire Post editorial operation, it is proposed to combine these two departments into one team.
“Working in this way will allow the company to address he duplication of jobs covered while still allowing each newspaper to develop in its own right. Our plan allows for title differentiation with some key journalists working exclusively for one product.
“Should this proposal go ahead there would be a total loss of 19 roles. To mitigate these losses voluntary redundancies were initially sought and 9 have been accepted; we will endeavour to minimise the impact of the remaining roles through further voluntary severance and redeployment.
“We anticipate that this consultation would be complete by the end of July 2012.”
The integration of the two titles began earlier this year with the announcement that the editor roles were being combined.
YP editor Peter and his YEP counterpart Paul Napier were expected to go head-to-head for the role before Paul landed the group-wide role of editorial development director.
The National Union of Journalists, which estimates the changes will save JP £600,000 a year on its wages bill, has already condemned the plan.
Joint father of chapel and office branch chairman Peter Lazenby said: “One again Johnston Press is responding to its financial situation with a policy of slash and burn.
“We know that regional newspapers are in decline, but the situation at Johnston Press has been vastly exacerbated by financial incompetence, mismanagement and bad judgement at the most senior levels of management.
“Over a period of years the editorial workforce at the Yorkshire Post and Yorkshire Evening Post has fallen by half. Circulations are in steady decline. The sacking of staff will simply reduce the quality of our papers and hasten their decline.”
General secretary Michelle Stanistreet added: “”These cuts will have a disastrous impact on journalism and demonstrate the glaring weakness in the strategy Johnston Press is banking on to claw the company back out its self-inflicted debt.
“Without quality journalism and properly resourced titles, the company has no chance of reviving its fortunes. ”
Peter said there would now be a union meeting of staff at the papers to discuss a response to the proposed job losses.
Currently there are believed to be around 123 editorial staff at the two papers. The union says the proposed job cuts represent 15pc of the workforce.
