The Fickle Operator / Fair-Weather Ally

One-liner: Loyal to you exactly until the moment it stops being convenient, then gone without a word.

What it is

With you until the wind shifts, then gone without a word.

Law 20 of Robert Greene’s The 48 Laws of Power instructs the reader never to bind themselves permanently to any side, faction, or person. Staying uncommitted, in Greene’s framing, keeps you desirable to everyone and dependent on no one, so you can shift allegiance the instant it becomes advantageous, without ever having spent your credibility on a losing position. Applied to a person rather than a strategy, this describes a recognizable workplace type: someone whose support, credit-sharing, and even friendliness are held in reserve, deployed toward whoever currently has power or is currently winning, and withdrawn, often overnight and without acknowledgment, the moment that calculus changes. The real-world anchor for this is the concept of opportunism formalized by economist Oliver Williamson in his transaction cost economics, defined precisely as “self-interest seeking with guile,” a willingness to break informal commitments, withhold relevant information, or exploit a partner’s trust whenever circumstances make it profitable to do so. Williamson’s point, borne out across decades of organizational-economics research, is that some relationships are maintained only as long as they remain useful, not because a contract or a felt loyalty binds them. That is exactly what distinguishes this type from ordinary self-interest: everyone acts in their own interest sometimes, but the fickle operator’s alliances are legible, in retrospect, as having never really been about the other person at all.

What it looks like (workplace)

Before: A program lead is driving a difficult systems migration. An adjacent team lead is her most vocal ally, praising her approach publicly in cross-team meetings and privately calling her main rival’s competing proposal “held together with tape.”

The incident: The CTO starts asking pointed questions about the migration’s cost overruns in a leadership review. Within days, the ally’s status updates start borrowing the rival’s exact phrasing. At the next cross-team meeting, with no transition and no acknowledgment, she says, “I’ve always thought we should keep both options open.”

The month after: The migration lead finds herself repositioned as “the one who overcommitted,” while her former ally now sits, visibly comfortable, next to the rival lead. Weeks later the migration clears its audit and regains favor. The ally reappears just as warm as before, offering to “help tell this story upward,” with no reference to the interval in between, as if it never happened.

How they operate

Two of the five moves below run constantly, in the background, whether or not anyone is watching; the other three are what a target actually experiences, in order.

1. Portfolio building (continuous). Warm, low-cost ties are maintained with every faction at once, committed to none, the social half of Weaponized Networking & Productivity/Visibility Theater. When factions clash, this person performs evenhandedness and stays off the record as a matter of standing policy, False Neutrality / Passive Deflection. It costs nothing yet, and that’s the point: it is pure inventory, kept liquid for later.
2. Riding the favorite. While your project has momentum, this person is your loudest defender, especially where the audience is largest, Playing to the Gallery. You reasonably price this as real loyalty and allocate trust accordingly. It costs you exactly that: the trust you extend here is the exposure stage 4 later cashes in.
3. The weather check (continuous). In parallel with stage 2, this person is constantly reading which way leadership is leaning. The first observable tell of a coming switch is hedging, “I see both sides,” and quietly going silent in meetings where they used to open for you. This is the entry’s highest-value teaching moment: the switch itself looks instant, but the hedge precedes it and is visible in real time if you’re watching for it, not just in hindsight.
4. The switch. Overnight, and with no acknowledgment, the person realigns: your rival’s talking points start coming out of their mouth, often paired with a retroactive continuity edit, “I’ve always had reservations,” which is Strategic Alignment After Deflection plus a light touch of Perception Management / Rewriting the Story applied to their own prior record. When the winning side is actively organizing against you rather than just prevailing, this stage is also how Coalition-Building / Mobbing recruits its rank and file. It costs you standing and narrative control at the exact moment you need both.
5. The return offer. If your position recovers, the warmth comes back too, offering help, acting as if nothing happened, with zero reference to the interval, Hoovering in its workplace form rather than its romantic one. It costs you the temptation to re-extend the exact trust that stage 2 already taught you not to.

Why they do it

Treating alliances as purely instrumental, useful only for as long as the other party has leverage worth borrowing, removes the drag of loyalty from every decision, letting the person move toward advantage with none of the friction that binding commitments would normally create. At the level of individual disposition, this maps onto Machiavellianism, the Dark Triad component defined by amoral manipulation and a constant, calculating read of who currently holds power, which is exactly why this pattern is weighted toward the Dark Triad on this site’s assessment: opportunism, in Williamson’s economic sense, is what Machiavellianism looks like when it’s operating openly, inside an organization, instead of in a lab measure. Constant monitoring in stage 3, instant realignment in stage 4, and a friction-free return in stage 5 are all the same underlying trait, not three separate decisions.

How to protect yourself

The support that counts is the kind that shows up when backing you is costly.

• Judge alliance by track record under changing conditions, not by current warmth. Stage 2’s warmth is cheap and universally available from this type; what actually predicts stage 4 is how the person behaved the last time backing someone got expensive.
• Watch for stage 3’s hedge, not just stage 4’s switch. “I see both sides” from someone who was previously unambiguous is the earliest honest signal you’ll get, and it arrives before the realignment, not after.
• Avoid depending on a single ally for political cover, since the arrangement can dissolve the moment your position weakens, with no notice, per stage 4.
• Don’t take the sudden absence of support personally as a verdict on your work. It’s frequently a read of the room, not a read of you.
• Keep your own record of who actually backed you when it was costly to do so. That list, built from stage 2 under real pressure rather than stage 5’s friendly return, is the one worth trusting with the next hard call.

Cross-links: The Dark Triad, the fold-parent trait cluster, opportunism-with-guile functioning as Machiavellianism operating out in the open; The Compulsive Repeater, the other pattern that only becomes visible once you compare notes across contexts; Coalition-Building / Mobbing, where stage 4’s switch supplies rank-and-file numbers to whichever side is winning; Divide and Conquer, the factional environment this pattern thrives in and needs to keep operating; False Neutrality / Passive Deflection, stage 1’s standing posture and stage 3’s hedge; Strategic Alignment After Deflection, the signature move of stage 4’s overnight realignment; Hoovering, the stage-5 return offer with no reference to the interval.

Label note: Opportunism, in Williamson’s sense, and Machiavellianism, in personality psychology’s sense, are both established, separately studied constructs, one in organizational economics, one in trait psychology. “The Fickle Operator” is a descriptive archetype built by combining Greene’s strategic framing with that real research, useful for naming a pattern of conduct, not for formally typing a person.
