The Responsibility Drift Loop

How work nobody assigned you becomes work everybody expects from you

This Insight explains how capable people end up carrying a second, invisible job assembled entirely from things they once helpfully covered — and why nobody, including them, ever decided it should happen.

Read this alongside any week where your job description and your actual week have stopped resembling each other.

The Core Pattern

A gap appears. Someone capable fills it, once, to be helpful.

Next time the gap appears, everyone looks at the person who filled it last time.

Within months it's simply “theirs” — no conversation, no decision, no title, no pay.

Multiply that across years and a capable manager is running an unofficial portfolio the organisation never chose to create.

Neither did they. It drifted.

The Loop

Gap → Capable person covers it once → Expectation forms → Ownership assumed → Load becomes permanent, never formalised → New gap appears → (repeat)

The drift compounds, because each absorbed task makes you more central — and more findable — for the next one.

How the Drift Is Created

Responsibility drift is fed by:

“just while we sort something out” with no end date
competence being the path of least resistance (“you’re so good at it”)
helpfulness being cheaper than a hiring conversation
the absorber’s silence being read as consent

Nothing here looks like exploitation.

That’s why it’s so hard to raise.

Two Ways the Loop Shows Up

The Temporary Cover

steps in during an absence or vacancy
the “temporary” quietly loses its end date
raising it now feels like letting people down

The organisation has stopped seeing a gap. It sees a solution — you.

The Talent Magnet

visibly good at something outside their role
becomes the unofficial go-to for it
the skill turns into a tax

Being good at a thing quietly becomes owning the thing.

Why Managers Miss It

From above, drift looks like:

things working
a reliable pair of hands
no problem to solve

The cost — the absorber's stretched capacity, stalled development, and slowly banking resentment — sits below the waterline until they resign or burn out.

Then everyone's surprised.

Why Advice Fails

Telling the absorber to:

“just say no”
“set boundaries”
“push back”

ignores that the expectation formed silently over months. There was never a moment to refuse.

You can't decline a decision nobody made.

A Better Question

Instead of asking:

“How do I get out of all this?”

Ask:

“Which of my responsibilities was ever actually decided?”

Then:

“I can cover this until [date] — then we need to decide whose it is”
What am I doing that my role would never mention?
What would happen if I listed the drift and showed my manager the list?
Where am I letting drift into MY team — because someone capable keeps quietly absorbing?
