As a strategy for dominating a situation, divide-and-conquer has a storied history. In The Art of War, Sun Tzu writes:
…the art of using troops is this: When ten to the enemy's one, surround him; When five times his strength, attack him; If double his strength, divide him…

The application of this strategy in the workplace is widespread. Here are some of the forms divide-and-conquer takes at work. See "Devious Political Tactics: Divide and Conquer: I," Point Lookout for July 6, 2005, for more.
- The three-legged race
- Some supervisors assign responsibility jointly to two people who are already at odds. This tactic can be a simple error, or even a misguided attempt to "give them a chance to work things out," but often its purpose is to keep the warriors in conflict, to protect the supervisor. See "Devious Political Tactics: The Three-Legged Race," Point Lookout for October 15, 2003, for more.
- If you really want harmony, work on the difficulty directly, possibly with professional guidance. Worries about your own position are better addressed by working on your own performance. Foster unity, rather than divisiveness, in your team.
- Delaying the decision
- When subordinates contend for the same promotion or for some other desirable assignment, some supervisors delay their decisions, on the theory that competition creates superior performance.
- Although performance might improve before the decision, this tactic can damage relationships permanently. And that could depress performance permanently after the decision — for the winner, for the loser, and for the entire group.
- Lying
- Divide-and-conquer
is most appealing
to those who
feel weak - One approach to dividing an alliance, or to keeping trouble alive, is to tell lies to one or both parties. Lies — either of omission or commission — can create the impression that one party threatens the other. See "Some Truths About Lies: I," Point Lookout for August 4, 2004, for more about lies.
- Disinformation of any kind is very risky, and it's especially risky to its source. After the immediate "benefit" fades, the disinformation can remain, limiting your future options.
- Delegating for conflict
- Delegating authority generally enhances effectiveness, but some managers delegate to create conflict by delegating different responsibilities to two people, in such a way that they must cooperate to succeed. Since neither one is fully responsible, the delegator is free to play one against the other.
- This tactic damages relationships and depresses organizational performance. Costs are high and repairs difficult, because they involve both reorganization and replacing people.
- Maintaining differences
- When managers have promised to retain employees in mergers or acquisitions, keeping organizational elements intact can be a divide-and-conquer tactic. Managers can then systematically discriminate in allocating resources and opportunities. A typical goal might be to drive up voluntary turnover in acquired units.
- Indirect subversion of the promise to retain employees is still subversion. This tactic is unethical, and therefore risky. If the promise to retain was sincere, subverting it could subvert a key strategy of the combination.
Divide-and-conquer might be effective on the battlefield, or when subjugating whole populations. In the workplace, though, it is ethically questionable. Managers who use it risk conquering only themselves. Top

Beware any resource that speaks of "winning" at workplace politics or "defeating" it. You can benefit or not, but there is no score-keeping, and it isn't a game.
- Wikipedia has a nice article with a list of additional resources
- Some public libraries offer collections. Here's an example from Saskatoon.
