The Hazards Campaign and the Centre for Corporate Accountability are calling on trade unionists to send a special email postcard to Tony Blair asking him why the Government has not introduced legislation creating the new offence of "corporate killing".
This is part of a campaign to bring home to the Government the strength of feeling about its failure to introduce legislation which would allow employers to be prosecuted for causing workers' deaths through their management failures.
The Government promised to reform the law five years ago. Since then over 2,000 people have been killed in work-related incidents or disasters.
A website has been set up that will allow you to easily send specially designed postcards to the prime minister (and your local MP) at www.hazards.org/postcard.
