Leaders at a small set of peer firms agree informally not to hire each other's departing people, so dissatisfied employees find their exit options closed and usually blame themselves.
An example
After twenty years in healthcare construction, a senior project executive at one of the four general contractors that built most of the hospitals in a mid-sized metro area decided to leave, having been passed over for a regional role. The other three firms knew her work well. She applied to all three over four months. Two never responded. The third scheduled a call, then canceled it without explanation. A recruiter told her the market was slow, and she began to wonder whether her reputation had slipped. Over coffee a year later, a retired executive from one of the firms told her about a standing understanding among the four chief executives, renewed each year at an industry dinner, not to recruit from each other's senior ranks. Nothing had ever been written down.
Why it works
Leaving looks worse, because the clean move to a comparable firm disappears and resigning means a long search of unknown length. It also gets costlier: lost income, a rejection pattern that becomes visible to one's network, possibly a move to another city. The employee usually reads the rejections as personal failure or a weak market, which keeps them in place without anyone having to defend the terms of their job. The pact relies on a small peer set whose leaders know each other, a role specialized enough that the peer set is the realistic market, deniable channels such as dinners and board overlaps, and an employee without the evidence or legal knowledge to challenge it.
The thinking behind it
Mark Granovetter The strength of weak ties, from The Strength of Weak Ties (1973): close contacts tend to know the same people and things, while acquaintances bridge to other groups and carry new information. A pact among a small peer set works through the dense network at the top of an industry. The defense runs through weak ties: acquaintances in adjacent industries and regions carry openings the pact cannot reach, and sometimes the news that the pact exists.
Jeffrey Pfeffer Resource dependence, from The External Control of Organizations: A Resource Dependence Perspective (1978): whoever controls a critical, scarce resource gains power over those who depend on it. When the realistic jobs for a specialist sit in four firms, those firms' leaders jointly control the resource the employee needs to leave. Widening the search reduces the dependence, which is why it comes first among the defenses.
Warning signs
Rejections, or silence, meet a qualified candidate at every firm in a small peer set while employers outside it respond well. Calls get scheduled and canceled without explanation. The leaders of the peer firms share dinners, associations, or board seats. Rejections cluster after a departure becomes known. Nothing about any of it is ever written down.
How to defend yourself
Widen the search beyond the peer set: adjacent industries, other regions, clients, and suppliers, where the pact doesn't reach.
- Log every application, contact, and rejection with its date, including who said what.
- Compare your results inside and outside the peer set. A sharp difference is evidence.
- Talk to others who left the same firms and ask how their searches went.
- Take the pattern to employment counsel. Agreements among competitors not to hire each other's people may violate antitrust law, and counsel can tell you what your record supports.
Wait for counsel's advice before confronting any of the firms.
How a leader shuts it down
Stay out of no-hire understandings with peer firms, written or not. If one surfaces, through a whistleblower, a subpoena, or discovery in litigation, the legal and reputational exposure dwarfs any retention savings. Keep people by giving them reasons to stay. If you hear of such an arrangement in your industry, take it to counsel.
