Fishburn Hedges chief executive Neil Hedges said: 'I think this result is pretty good for the PR industry. There is a sweatshop culture at some firms in our industry.'

Survey questionnaires were completed by up to 250 employees from each organisation. Hedges says his company entered it as part of a recruitment and retention drive.
'We don't have a human resources department as such,' said Hedges.
'What we don't want, however, is the situation where the company becomes a place that people think of as a place for ball games and the like. Although it sounds trite, people come here because they like doing their best for clients,' he added.
