 You're not building a working class movement anywhere. You're just an advocate probably doing the work on behalf of workers in the union context anyway. If you're a left or progressive trade unionist, you understand from day one that there's a strategy. There's something that you do on day one, day two, day five, year one, year two in a new labor market area. But if you're a left trade unionist, you are by definition building a working class movement on issues that are not just in the contract.
