Indeed, that's a very interesting question.
The Reform Act came into force and was implemented before the labour code was put in place. I will say my preliminary opinion is that they govern different things.
As you know, caucuses have to decide which portion will be applicable to their caucus. It applies to the membership and expulsion of members, and leaders may be subject to a vote by their caucus. I would not qualify the exercise of a power under the Reform Act as a potential act of harassment, as members are exercising their rights under the Parliament of Canada Act. It's the same thing when they are participating in proceedings in the House and voting.
I'm afraid that's all I can offer today, but that is, indeed, a very interesting question.
