Great stuff, if you want to build workers power in your area then you’re taking a step in the right direction by getting active. Please take the initiative and message them first; I’d recommend being polite but firm in wanting to get your foot in the door asap. 9 times out of 10 these guys will forget you exist on their list of names to ring. In the best cases this is just because they just have a lot on their plate, but often its because their work ethic is bad. Don’t let that stand in the way of you getting some skin in the game.
