Event Details

Workshop Information

The Department of Justice (DOJ) held a public workshop on September 23, 2019, to discuss the role of antitrust labor markets and promoting robust competition for the American worker. The workshop was the first in a two-part series hosted together with the U.S. Federal Trade Commission. The workshop covered a variety of labor competition issues, including, among other topics:

  • Anticompetitive no-poach and wage-fixing agreements
  • Approaches to labor market definition
  • The role of employer collaboration and contractual arrangements between employers on competition for workers
  • Labor monopsony in merger enforcement
  • Antitrust exemptions for union activity and collective bargaining

Panelists discussed recent developments in the law, economic research, and policy proposals, as well as how to effectively develop cases challenging labor monopsony.

Assistant Attorney General for Antitrust Makan Delrahim opened the workshop, which brought together economists, attorneys, labor representatives, and industry experts who examine competition in labor markets and who have experience litigating or studying labor antitrust cases.

The Division explored the practical considerations that antitrust enforcers and private litigants face in bringing cases that involve labor markets. The workshop began with an overview of the status of labor economics, followed by a series of panels examining:

  • Approaches to defining labor markets
  • Antitrust analysis of labor restraints arising out of competitor collaborations and contractual partnerships between employers
  • Statutory and nonstatutory antitrust exemptions for labor union activities

The second day of the workshop was hosted by the Federal Trade Commission on January 9, 2020 and focused on the legal, economic, and consumer protection issues associated with the use of noncompete clauses in employment contracts. The workshop examined the current state of economic research on the effects of noncompete clauses, and whether additional research would allow the agencies to better understand the short-term and long-term micro and macro effects of such clauses.

Panel 2: Ancillarity, Collaborations, and Contractual Arrangements: Assessing Antitrust Harms in Complex Business Settings

Video iconView Panel 2.

Restraints on worker mobility are not always purely horizontal or purely vertical, and they sometimes arise in complex business settings, including a variety of collaborations, that blur the lines between interbrand and intrabrand competition. The panel explored recent developments in the case law and economic literature and discussed how antitrust enforcers should assess restraints on worker mobility, including restraints that arise within franchise systems and for workers in the “gig” economy.
