TRADE unionists from Huddersfield will be marching through London for their pension rights on Saturday.
Workers are protesting at moves to rise the retirement age to 70.
They argue that if the age is increased, manual labourers would work until they literally dropped.
Campaigners claim almost half of men in the country's poorest areas, including Doncaster and Bradford in Yorkshire, die before they reach 70.
Bob Stoker, Huddersfield Trades Union Council secretary, said: "In the public sector there are proposals to make staff work longer for a decent pension and delay early retirement options.
"All this at a time when directors of many companies are gaining fatter salaries and fatter pensions."
The march departs from Temple tube station at 1pm to gather in Trafalgar Square an hour later.
The theme will be opposition to firms withdrawing from good pension schemes.
In Yorkshire, one in three men die before they are 70.
TUC members are calling for a reinvigorated state pension linked to the rising prosperity of the country with compulsory contributions from employers.
