Catherine Swift is the chair of the Canadian Federation of Independent Business and also the spokeswoman for a new organization running advertisements targeting unions called Working Canadians.
The group is in part a response to the Working Families coalition, which has run ads against the Progressive Conservatives in past provincial campaigns.
The Working Canadians campaign comes at a time when Tory leader Tim Hudak is planning to change Ontario's labour laws to make union membership optional.
Swift was Ontario Today's guest on Thursday, where we asked whether unions standing in your way at work, or if they've helped you thrive.
Swift took part in live chat afterwards, which you can check out below.
