First... welcome to the board Ken! The folk's calling for "card drives" are company loyalist/trolls. There is no better way to divide and conquer the membership than to suggest they need to replace the collective bargaining unit. As you stated, this hasn't, and WON"T work!
As a purveyor of truth, expect personal attacks and claims that you are a union boss, officer, media rep, etc. This will all come from the same handful posters here whom are hellbent on fulfilling the promise to fracture solidarity, all in the name of their corporate sponsors!
