Men are more likely to take grievances at work to employment tribunals, new figures suggest.
According to the Department for Business, Innovation and Skills, 60 per cent of claimants in 2008 were male.
It based its findings on a survey of the tribunal applications from the 12-month period.
Meanwhile, the department - which aims to create a competitive economy, help businesses, promote innovation and give people the skills they need to succeed - said managerial workers also figured highly in the data.
Additionally, people aged over 45 were found to be more likely than younger staff members to take legal action against the organisations employing them.
The private sector bore the brunt of such legal action, with 72 per cent of cases involving such enterprises.
It was also revealed that use of mediation was low during the 12-month period, with nine per cent of claimants and seven per cent of employers taking such measures.
