Engineering union Amicus is due to launch an anti-bullying project today warning that the problem is costing the UK economy £1.3 million a year.
Amicus has set up a new website offering advice to sufferers on how to deal with bullying colleagues, customers or bosses.
More than two million people were bullied at work, which had a 'devastating' effect on individuals as well as on industry, said the union.
Mandy Telford of Amicus said: 'Bullying is a widespread and serious problem and one which none of us can afford to ignore.
'Thanks to the support of the Department of Trade and Industry we will be working with some of the UK's foremost employers to eradicate bullying and its root causes to create a culture of respect across workplaces in the UK.'
