When to leave a job and when to stay

The decision to leave a job is one of the most consequential career decisions most professionals make, and most do not have a framework for thinking about it. They wait until something pushes them, and the push usually comes from the wrong direction. A frustrating week. A bad performance review. A manager who said the wrong thing in a meeting.

The push reasons are real, but they are not the right reasons to leave. The right reasons are structural. This is how to think about them.

The six questions

The decision becomes clearer when run against six questions. Each question evaluates a different dimension of whether the role still earns you something.

Question 1: Are you still learning?

The question is not whether you are still being intellectually engaged. The question is whether the things you are learning are durable.

A role where you are learning a specific tool that will be obsolete in three years is teaching you something temporary. A role where you are learning how to navigate complex stakeholder dynamics is teaching you something durable.

The test: would the lessons of this role be useful in your next three roles, or only in this one? If only in this one, you have hit the learning ceiling. Time to consider moving.

Question 2: Is the trajectory still going somewhere?

Most professional growth is non-linear. Periods of fast progression alternate with plateaus. The plateaus are not the problem. The plateau without an endpoint is.

If you can see the next two career steps from where you are now, the trajectory is still alive. If the next step is unclear, or if the next step would require you to wait for someone above you to move and there is no sign of that movement, the trajectory has stalled.

A stalled trajectory is the strongest argument for leaving. Stronger than salary, stronger than role frustration, stronger than most other reasons people give.

Question 3: Is your work still respected?

Respect is not the same as praise. You can be praised in a role where you are not respected. You can also be respected in a role where you are not praised.

The test: when you make a recommendation in a meeting, is it weighed seriously, or is it filed alongside the other voices in the room? When you raise a concern, is it explored, or is it deflected?

A role where your contributions are no longer weighed at the level they were two years ago is a role you have outgrown, regardless of whether the title or salary has changed.

Question 4: Is your manager still useful to your career?

The relationship with your manager is the most important variable in your career, more than the company, more than the role, more than the industry.

A useful manager is one who advocates for you in rooms you are not in, who challenges you on the things you cannot see, and who connects you to people you would not otherwise meet.

A useful manager does not have to be the manager who likes you most. They have to be the manager whose judgement, network, and seniority make a tangible difference to where you are heading.

If you have outgrown your manager's career stage, and you cannot move to a different manager inside the company, the calculus changes.

Question 5: Is the company still a useful platform?

Some companies are platforms that compound. The brand on your CV opens doors three jobs later. The relationships you build there last decades. The skills you develop are valued elsewhere.

Other companies are platforms that decay. The brand does not carry. The relationships are local. The skills are specific to systems no one else uses.

Companies move from platform to platform-decay over time. A company that was a strong platform when you joined may not be one now. The question is not whether it was a good choice five years ago. The question is whether the next two years there will compound or not.

Question 6: Is the cost of staying becoming visible?

Every role you stay in past its useful life carries a cost. The cost is invisible at first. It becomes visible later.

The cost shows up as: a CV that no longer reads as recent. A network that has narrowed. A skill set that has plateaued. A confidence that has eroded. A salary that has fallen behind market.

The visible cost is usually the last to appear. By the time you can see the cost clearly, the cost has been accumulating for two or three years.

The test: if you imagine yourself in this role for another two years, what would you give up that you cannot get back? If the answer is "nothing important," staying is fine. If the answer is "the option to make the next move," that is the answer.

When to stay

The questions above can produce a lopsided picture, where every reason to leave looks valid and the reasons to stay disappear. This is not how the decision works in practice.

There are real reasons to stay even when the questions point to leaving:

A specific upcoming opportunity inside the company that is genuinely a step up.

A current programme of work that is at a critical stage and where leaving now would damage your reputation and the work itself.

A personal life situation that makes a job change disruptive at the wrong time.

A non-compete or vesting situation that makes the financial calculus worse for leaving in the next 12 months.

These reasons are real. The danger is letting them grow into permanent reasons to stay.

If you are using a real reason to stay, give yourself a deadline. "I am staying until this programme ships in March, then I am leaving" is a defensible decision. "I am staying" without a deadline is drift.

The honest version of the calculus

The honest version of this calculus involves saying things to yourself that are hard to say out loud.

The honest version involves admitting when a manager has stopped being useful, even though you like them. Admitting when a company has stopped being a platform, even though you have invested years there. Admitting when your work is no longer being respected, even though no one has said so directly.

These admissions are uncomfortable. The discomfort is the cost of accuracy. The cost of avoiding the admissions is the cost of staying past the point where you should have moved, and that cost is much larger.

The professionals we work with most often are professionals who have stayed too long, not too little. The CV they bring to us is the CV of someone who is two years overdue for a move, and the work of writing the CV is partly the work of accepting that.

If you are reading this and recognising yourself, the recognition is the answer. The next move is the work of preparing to make it.
