The cuts will mark the third round of redundancies this year.
Newsquest has announced that it will cut a further 20 jobs at its Herald and Evening Times newspapers as it tries to make further savings to compensate for a decline in advertising revenue.
Up to 20 editorial jobs will be lost in what will mark the third round of job cuts at the Glasgow publications in the last year.
A statement from Newsquest said the newspaper group was "making savings in its editorial department following substantial weakness in newspaper advertising revenue and anticipating continued income challenges ahead".
The company says it continues to make good digital progress “but has to contain costs to ensure the long-term success of the business.
National Union of Journalists (NUJ) national organiser, Paul Holleran, branded the cuts "beyond belief" and warned to expect "further restructuring" in October.
He added that the cuts were “not sustainable to meet budgets and maintain newspapers by constant cuts and savings” and described the scale and frequency of the job losses as “unacceptable”.
Holleran pointed out that “other groups have grown profits in recent years by investment and using basic methods of running newspapers and Newsquest need to change direction as the current route is all downhill”.
The company has advised staff that between 18 to 20 roles will be affected and has opened a voluntary redundancy programme.
