Nearly half (43%) of employees would like more responsibility in their current role, but a fifth of managers do not trust their staff to deliver.

According to research of 2,452 employees by YouGov for Investors in People, 43% of managers think staff would be concerned about the extra workload of more responsibility but only 8% of employees thought it would have a negative impact on their performance and only 4% felt it would make them less motivated.

In fact if staff were not given more responsibility 59% say they would become demotivated and 58% would be frustrated.

But 53% of staff have never asked their manager for more responsibility and 29% do not think there is an opportunity for them - with 15% believing their manager to be too controlling.

Simon Jones, chief executive of Investors in People, said: "By taking everything on themselves, managers can leave almost two-thirds of their people feeling demotivated and two-fifths could end up looking for a new job. In other words, giving employees the right level of responsibility is vital to driving the productivity of organisations through their people."
