Author, Professor Adam Grant, used research led by Michael Housman, which looked at 30,000 customer service agents in order to determine their commitment to their job.
Mr Housman suspected that the workers’ employment histories would give the biggest indication of their job commitment.
However, his results showed that employees who had held five jobs in the past five years were not any more likely to leave their positions than those who had stayed in the same job.
Instead, Mr Housman’s team looked at the internet browsers that each employee used.
Surprisingly, the results showed that employees who used Firefox or Google Chrome to browse the web remained in their jobs 15 per cent longer than those who used Internet Explorer of Safari.
