Delegates at the Brighton conference will argue today that as life expectancy increases and state and occupational pension ages rise, fewer workers enjoy a healthy retirement.
Officials will criticise the rise in the state pension age to 68 and warn that this could increase, forcing people to work longer.
The conference will press the TUC to co-ordinate campaigns against cuts in pensions and is expected to call for new research which can be used to show that "working longer means living less".
Calls will also be made for an independent commission into the state pension age and early retirement age.
Pensions will be a focus of marches being held on October 20 against the Government's austerity measures.
