Labor law protects something most workers do not know they have: the right to act together about working conditions, whether or not a union is involved. This article explains what Section 7 of the National Labor Relations Act actually covers, why an individual complaint is unprotected while the same complaint made with a coworker is protected, and how that distinction decides most cases. It walks through an organizing campaign from the first conversation to the election, what employers may and may not do, and what happens when they cross the line. Separate parts address collective bargaining and the duty to bargain in good faith, the grievance and arbitration system that replaces at-will employment in a represented workplace, the union's duty of fair representation toward its own members, and the rules governing strikes, pickets, and lockouts. It also covers the sharply different rules for public employees and for workers excluded from the Act entirely. Examples run throughout.
