One side outlasts the other in a long negotiation, with more stamina, more people to rotate, and fewer obligations elsewhere, until the other side concedes terms it resisted early on.
Borderline: whether this move is justified depends on the situation, and only the person in it can judge.
An example
By the estimate of the head of regional partnerships at a major airline, its capacity agreement with a regional carrier overpaid by about $40 million a year. With six weeks left on the contract, she scheduled the renewal session at headquarters and brought a team of seven from pricing, fleet planning, finance, and legal, who rotated in pairs through the day. The regional sent its chief executive and finance chief. She kept the agenda to the open terms and raised no new demands as the evening went on. By ten that night the regional had accepted a lower rate per block hour. At two in the morning its finance chief agreed to share fuel-price risk above a cap. Both sides signed a term sheet before breakfast, and the agreement ran its full seven years.
Why it works
Every extra hour raises the price of holding a position for the side with fewer people: lost sleep, missed obligations, pressure from its own principals to close. Conceding gets cheaper by contrast, since it ends the session. As fatigue sets in, positions that felt important at hour two feel like hairsplitting at hour ten, so the stand loses value. It works when one side can credibly outlast the other through more people, fewer outside commitments, or willingness to sit. It fails when stamina is equal, deadlines bind both sides, or the other side can walk away and reconvene.
The thinking behind it
Thomas C. Schelling In The Strategy of Conflict (1960), Thomas Schelling argued that in bargaining the power to bind oneself can be a source of strength: a party that visibly gives up its option to retreat forces the other side to adjust. Bringing a rotating team and saying plainly that you will stay until terms are agreed is a commitment of this kind. It makes your willingness to outlast the other side credible, so the pressure falls on them.
Ronald H. Coase Ronald Coase, in The Problem of Social Cost (1960), argued that because bargaining is costly, the cost of negotiating shapes the outcome. A long session raises that cost unevenly: the side with fewer people and more obligations pays more for every hour. The defenses in this page, such as agreed stop times, fixed dates to reconvene, and enough people to rotate, work by evening out the cost of continuing to bargain.
When it fits
Worth considering when you have a real stamina advantage (a larger team, fewer competing obligations, a deadline that costs the other side more), the terms at stake justify a long session, and the relationship will survive hard bargaining. It needs authority to agree terms in the room.
How to use it well
Staff for length. Bring enough people to rotate and someone with authority to close at any hour.
- Hold the session where and when it suits your team, and say plainly that you are prepared to stay until terms are agreed.
- Keep to the open terms; new demands late in the session read as bad faith and give the other side a reason to walk.
- Offer breaks when asked, and accept a fixed date to reconvene if they insist.
- Write the agreed terms down as you go, so nothing reopens at dawn.
The other side will see the asymmetry. Stamina is a fair advantage when it is visible.
What it costs and where it backfires
Terms won by exhaustion can come back: the other side's principals may refuse to ratify, and the people who signed at two in the morning remember. Relationships you need for years carry the cost. Observers may read the length itself as bad faith, and the next negotiation will start with a cap on session length. The move needs nothing beyond stamina; false deadlines, threats beyond your authority, or misstatements about your alternatives take it over the line.
When it is used on you
Recognize sessions running hours past their end, the other side rotating fresh people while yours stay, and hard issues held for late. Agree a stop time in writing before talks begin, bring enough people to rotate, decide which terms you will not settle after a set hour, and propose reconvening on a fixed date when a session runs over.
