Staff at Independent Newspapers face losing nearly half of their pension benefits.
The company is also proposing that they work to the age of 68 as part of plans to plug a hole in the pension fund.
The plan includes workers at the newspaper group being given a 5% stake in the company.
The company's defined benefit pension scheme has a deficit of more than €150m.
If the proposals put forward by management are accepted, staff will get to keep 54% of the pensions they were promised.
The cuts do not affect existing pensioners.
