New research by the Health and Safety Commission (HSC) shows that Scotland is the most dangerous country to work in the UK.
The HSC report shows that 37 people lost their lives in workplace accidents in Scotland in the period 2004 to 2005.
The T&G union called on the Scottish Parliament to take urgent action and introduce corporate manslaughter legislation.
T&G Scotland regional secretary, Mike Brider, said new legislation should include custodial sentences for executives found guilty of negligence that leads to the death of a member of staff.
So far the UK government has refused to make bosses personally liable for deaths at work.
