Almost one in five adults believe they have missed out on a job because of their background, accent or social status, research suggests.
The Co-op said its survey of 8,500 people found that one in 10 have been teased over their accent, leading some to change the way they speak during a job interview.
The company said it was taking action to tackle the issue after its study revealed that many people believe the opportunities available to them are fewer and the outlook tougher, because of their background.
