The AA has been accused by the GMB union of trying to make 431 recovery patrol staff take redundancy.
The union said patrol staff have been sent a letter saying that most were very committed to the AA and its members, but a few workers were falling short.
Staff who meet company expectations will receive £2,000 in recognition of their work, but those below standard will be offered £18,000 voluntary severance.
The AA denied the GMB’s claims, saying a maximum of 20 jobs would go.
GMB official Paul Maloney said: “The venture capitalists currently running the AA are seeking to force 431 patrol staff out of a job.
“The company is asking them to sign confidentiality agreements in return for giving up their jobs.”
The AA said it had been reviewing the performance of patrols, as part of an “ongoing business transformation”.
