The Treasury Board has some responsibility for the public service. However, since Minister Hajdu is responsible for matters such as worker protection and their safety in the workplace, it is up to her to amend the Canada Labour Code in order to ensure that protection. I am sure that she would be willing to make any required amendments in the area.
The minister would certainly be open to increasing protection for workers. Discussions with union representatives have actually taken place in order to improve working conditions in Canada.
