Unions often negotiate. It's a big part of what we do. When you're going into negotiations, you don't necessarily take difficult things off the table before you get to the negotiations. You want to keep all the bargaining chips you could possibly have in your tool box so that when they're asking you to give something up for something you want, you have something you can give up, potentially. You also want to work towards a longer-term goal where you're normalizing the idea that carbon price fairness, levelling the playing field, is something you want long term.
