We Do the Work

The AFL-CIO represents America's Labor movement, which is not something I'd brag about.

Anyhow, they say that Federal and state laws guarantee people the right to form unions and that "eligible employees have the right to express their views on unions, to talk with their co-workers about their interest in forming a union, to wear union buttons, to attend union meetings and in many other ways to exercise their constitutional rights to freedom of speech and freedom of association."

The key word for part-time TAs and freelancers is probably ELIGIBLE...or maybe BUTTONS.
