More people are claiming compensation for accidents which happen at work, a new report by the TUC suggests.
British companies paid out £305m for personal injury claims in 2001, says the body.
Around 53,000 new legal cases were taken by unions in 2001 - an increase of 3% on the previous year.
Employers who had shown "scant regard" for the health and safety of their employees have wasted £3bn over the past decade by paying for the cost of accidents at work, says the TUC.
Most claims continue to concern stress in the workplace.
In 2001, around 2,500 new stress cases were started while 1,000 claims were asbestos-related.
"We would like to work more closely with employers and insurers to make sure accidents are avoided and illness prevented," said TUC head Brendan Barber.
"But until workplaces are safer, we will continue to make sure victims get justice."
