Question: A company employs largely part-time staff, and in the past has found staff turnover to be 23 per cent each year (that is 23 per cent of staff in any one year leave the company). This is felt to be too high, with implications for morale, motivation and costs (since new staff have to be recruited and trained). The company has recently put into place a performance management system intended to improve productivity, morale and staff retention. The latest figures based on a sample of 20 teams of staff in the company indicate staff turnover is 18.6 per cent, standard deviation 1.7. Is there any evidence that staff turnover has fallen?
