People & HRSomeone applying and interviewing

When I decide to leave, I want to go well, so I do not lose relationships built over years.

Khi tôi quyết định nghỉ việc, tôi muốn ra đi tử tế, để không mất những quan hệ mình đã xây trong nhiều năm.

Job context

No idea when to say it
High
Early is risky and late is discourteous.
Root cause: An organisation's reaction to a resignation is unpredictable
There is nobody to hand over to
High
The replacement has not been hired.
Root cause: Recruiting a replacement starts only after the resignation
Treated differently after resigning
Medium
Though still working there.
Root cause: Whoever is leaving is treated as already outside
The exit interview leads nowhere
Medium
So nobody is honest in it.
Root cause: Honesty at that moment benefits the speaker not at all
A reference is still needed later
Medium
So goodwill must be preserved at any cost.
Root cause: A former employer keeps the right to speak about you after you leave

A solution is not the same thing as a product, a customer can hire a behaviour or a workaround too.

Give exactly the required notice
Behaviour
The safest route, usually too short for a proper handover.
Write things down before leaving
Behaviour
The most generous thing possible, counted in nobody's workload.
Warn the immediate manager informally
Behaviour
Best preserves the relationship, and is a bet on trust.
Answer blandly in the exit interview
Workaround
The only rational response, leaving the organisation never knowing the real reasons.
Stay in touch with colleagues afterwards
Behaviour
What actually remains, outside every process the organisation has.

Honesty in an exit interview gains the speaker nothing and may cost them a reference, so the organisation collects precisely the most harmless answers.
Why existing solutions fail: The only person free to speak plainly about an organisation is the one leaving, and they are also the one who still depends on it for a reference, so the window of honesty closes exactly as it opens.
Potential opportunity: Collecting reasons anonymously and months later, when the teller depends on nothing.
There is a process for joining and a process for having left; the middle, someone still working who has resigned, belongs to neither.
Why existing solutions fail: This period is when knowledge is most transferable and also when the organisation treats the person as already outside, so most of what they know leaves with them during exactly the weeks that should have been the most valuable.
Potential opportunity: Treating the notice period as a stage with its own work, transferring knowledge, rather than as a wait.
