Almost one-third (31%) of respondents said they would leave their position, compared to only 22% who would speak to HR for advice.
The poll also found that a quarter of respondents had lost sleep and that around one in seven (16%) have had to take sick leave due to a bad manager.
Alex Swarbrick, a senior consultant at Roffey Park, said the findings were shocking but not surprising. “In our 2014 survey, roughly half of managers reported having observed misconduct in their organisations – that included abusive or intimidating behaviour through to ethical misconduct.
"We found 54% of those who had observed misconduct said they were looking for another job.”
Good managers can have an inspiring effect on their team. Over half (56%) of the Penna survey respondents have learnt how to motivate others from a good manager, while 42% have learnt how to run a team.
However, one in five (20%) would not accept a job offer if they knew the manager had a bad reputation.
Penny de Valk, managing director of Penna's talent management practice, said organisations could be losing out on talent. “To put it simply, people join great companies but leave because of bad managers. Good managers can be your best retention tool – inspiring, motivating and engaging your teams to get the very best out of them.”
