Trade union Amicus is calling for employers to contribute to a minimum pension for staff.
Derek Simpson, Amicus joint secretary, wants the Government to introduce compulsory pensions contributions for both employers and staff.
He said their should be a minimum contribution from employers of 10 per cent, and 5 per cent from staff.
Amicus wants the Government to fund employers who will struggle to run their own scheme through government bonds.
"The argument for a minimum is clear," Simpson said. "There should be a commitment by staff but employers must be compelled to make minimum contribution to their employees' pension regardless of structure.
"The immediate cost of a minimum pension would be low, while the cost of not introducing compulsory pensions contributions will be devastating both to individuals facing poverty and to the economy burdened by dependants."
Amicus' is hosting a pension conference today.
