Kleinwort Benson Private Bank tends to motivate staff on an individual basis, by assessing each new employee in order to identify what drives them at work. This insight is used to develop a clear career progression path within the firm for the bankers, which, combined with bonuses, helps keeps them well motivated.

Diane King, director of HR, says: "I think when employees are at the younger end of their career they are motivated by seeing successful staff ahead of them."

Although the bank believes that offering some sort of work-life balance to its high-earning employees is important, King admits that there are some restrictions to this when working in the City. "We are concerned about work-life balance but there needs to be some commitment to the client to do what needs to be done," she says.
