Antipoaching (or no-poach agreement) is an anti-competitive conduct where companies conspire not to hire each other's employees.
[1] Antipoaching agreements, or no-poach agreements, are related to non-compete clauses, but distinct -- no-poach agreements are among employers, non-compete clauses are between employer and company.
In the United States, antipoaching agreements have been widespread among franchise businesses: Research has found that 58 percent of major franchisors' contracts in 2016, including those of McDonald's, Burger King, Jiffy Lube, and H&R Block, contained agreements not to hire the workers of other franchisees.
[3] Antipoaching agreements may be illegal under U.S. antitrust law in some circumstances.
