A comprehensive treatment of private-sector labor law for employers, unions, and counsel. Part I builds the statutory architecture: Section 7 rights, the Section 8(a) and 8(b) unfair labor practices, the coverage exclusions including the narrow supervisor definition, and the Board's structure and procedure. Part II covers organizing and elections: how campaigns begin, authorization cards, the representation petition and its timeline, bargaining-unit determination and its oscillating standards, lawful and unlawful employer campaigning under the TIPS framework and Gissel, benefit grants under Exchange Parts, property access under Lechmere and Republic Aviation, the Excelsior list, objections, and the Cemex framework that can produce a bargaining order without an election. Part III covers collective bargaining: exclusive representation, mandatory permissive and illegal subjects, the duty to furnish information, good-faith bargaining and surface bargaining, unilateral change under Katz, impasse and implementation, contract administration and grievance arbitration, and successorship. Part IV covers economic weapons: protected and unprotected strikes, permanent replacement and reinstatement rights, lockouts, picketing limits, and secondary activity. Part V covers union security, dues, and right-to-work. Part VI covers remedies, Section 10(j), and the doctrinal instability that makes verification essential.
