The collaboration aims to offer practical and meaningful support to jobseekers searching for their next role.
Hayley will front Fish4jobs' regional job fairs, providing face-to-face advice to jobseekers in her trademark no-nonsense style.
She will also host a series of online career workshops hosted by Fish4jobs with practical advice on writing an effective CV and giving a successful interview.
Hayley has considerable experience in working with jobseekers from her days at the Welfare-to-Work agency and recruiter A4E, which eventually led to the Fairy Jobmother series on Channel 4.
She said: "This partnership with Fish4jobs provides me with the right platform to reach people looking for their next job."
Sarah EL-Doori a director at Fish4jobs, said: "At Fish4jobs we want jobseekers to find the right job to match their skills and experience. Hayley is a fantastic ambassador for us with her practical approach and success rate at helping people find a new role."
