A proposed law to improve the safety of overnight shift workers has won the support of some people in Yorkton, Sask., where a gas station attendant was killed on the job in June, 2011.

Friends and family of Jimmy Wiebe were among the first to sign their names to a petition, in support of a new law that the NDP opposition has proposed.

What has been dubbed 'Jimmy's Law' would require businesses with overnight shifts to either schedule at least two workers to cover the shift, or provide a secure workspace such as a locked door or bullet-proof barrier.

The NDP have been calling for the changes and have introduced a private member's bill in the legislature.

The party's labour critic, David Forbes, is visiting night-shift workers to experience their working conditions.
