The survey interviewed 300 executives agencies and in private and public sector in-house roles. Eighty per cent were in their second jobs or beyond.
Respondents said career progression was their most regular reason for leaving an employer - some interviewees were in their fifth job.
While an average of 93 per cent of PROs in all age groups thought they would still be in PR in a year's time, only 66 per cent of 22 to 25-year-olds said they would definitely be in PR in five years' time. Sixty-eight per cent of 31 to 35-year-olds gave the same response.
Ketchum London chief executive David Gallagher asked: 'How do we make people's second and third jobs in PR more attractive? It is clear that people only give their best when employers give the best to them.'
