Honda is trying to raise the age of retirement to 62 at its British plant in order to prevent a crisis in its pension fund.
According to the BBC Online, the move comes as the car-maker begins its first pay talks with unions since it started manufacturing in the UK 17 years ago.
Honda needs to raise the retirement age to boost its pension fund, which has a £40m deficit.
The group is also closing its final salary pension scheme to new entrants for the next five years and asking employees to increase their contributions.
Honda is thought to be the first major employer in the UK to try and raise the age at which its staff can retire.
