Scope creep never announces itself. It arrives as a compliment.
"Can you keep an eye on Priya's projects while she's off?" Then Priya leaves and isn't replaced. Then "you're closest to it, can you own the vendor reviews?" Eighteen months later you're doing 1.4 jobs on 1.0 salary, and every step felt reasonable at the time. It felt like being trusted. That's exactly why it works, and why the defence has to be a standing protocol rather than a mood you reach when the resentment finally lands.
The operating principle: unpriced work stays unpriced. Silence, in organisational terms, is consent, and by the time you're resentful you've usually been consenting for a year. The protocol prices the work at the moment it arrives.
Stage one: the acceptance receipt
The moment extra scope lands, accept it visibly, with a clock: "Happy to take that on. Let's note it sits outside my current role, and put a review date in for three months."
One sentence, said warmly. It converts an invisible favour into a recorded expansion with a date attached. There's no conflict in it; you've said yes. You've just also opened a ledger entry, and the awkwardness of saying it lasts exactly one repetition. Follow with a one-line email the same day so the entry exists in writing: "As discussed, I'll pick up X alongside my role; review pencilled for November."
Stage two: the review
At the date, arrive with the evidence file (day 2): "I've run X alongside my role since August. Here's what it's delivered. I'd like to make it formal: title, pay, or both."
Note the position you're negotiating from, because it's the strongest one that exists in salaried life: the goods are already delivered, the capability question is already answered, and the only open item is pricing. Compare that with asking for a promotion into work you haven't done yet. Interim delivery, priced correctly, is the fastest promotion route there is; priced never, it's the slowest.
Stage three: the handback option
If the answer is "not the right time": "Understood. Then let's agree what happens to X in the meantime."
Said calmly, this lands the economic reality: work that costs the company nothing has no reason to ever cost something. Your genuine willingness to hand the scope back is what makes the whole ledger real, and in my years on the approving side, this sentence produced more "let me see what I can do" than any quantity of pleading. Sometimes you'll hand the work back, and that's a good outcome too: you've converted unpriced obligation into capacity.
The audit for existing creep
Most readers are already carrying unpriced scope, so the protocol needs a retroactive entry point. List everything you now do that wasn't in your role twelve months ago. If the list surprises you, open the ledger this month: "I want to review how my role has evolved; I've listed what's been added over the year." The conversation is stage two, arrived at late, and late beats never by a wide margin.
Why this compounds
People who price scope reliably get handed scope differently: with budget attached, because the asker has learnt that the ledger exists. People who absorb scope silently get handed more of it, for the same reason water flows downhill. Both reputations compound. Choose which one deliberately.
