I'll be more fulsome in 30 seconds.
I would add one thought to all that. Resources on both the bargaining agent's side and the employer's side are unfortunately not always focused at the same time on those issues. Bringing them all into the same room for the same process would make sure that a fulsome discussion happened once every three or four years through the bargaining process. All the expertise would be at the table, as opposed to having—as is often the case in big unions—a team of people doing collective bargaining, and a separate team in another branch doing pay equity analysis.
Thank you.
