An increasing number of employees in the UK have been subject to workplace bullying, it has been found.
According to research conducted by Unison, which claims to have more than 1.3 million members, over a third of people polled had experienced such victimisation over the last six months.
This represents a rise of almost double since a similar survey conducted in 1997.
Unison general secretary Dave Prentis described the statistics as "shocking".
He added: "Workers have the right to earn a decent living in a safe environment. They need to be treated with respect and not forced to take time off work because bullying has made them ill."
Mr Prentis went on to point out that it was recently shown that a total of 13.7 million working days are lost each year due to stress and depression experienced by employees.
Among the most frequently cited complaints of those polled were rudeness, criticism, excessive work monitoring, exclusion and intimidation.
