Resignation is treated as an ending. In practice it is the start of a long, quiet relationship in which former colleagues describe you to people considering hiring you, sometimes years later and usually informally.

Sectors are smaller than they appear. The person you leave holding an unfinished project becomes a hiring manager, a client, a peer on a panel. Almost nothing you gain by leaving badly survives that arithmetic.

The good news is that leaving well is mostly a sequencing problem, and the sequence is short.

Tell your manager first, and tell them in person

Before the team, before the friend two desks away, before any public post. If your manager hears it from someone else, the relationship ends there, and that is the relationship every future reference request goes through.

Ask for fifteen minutes, say plainly that you have accepted another role, name your intended last day, and say you want to hand over properly. Do not open with a justification. You are informing, not requesting, and the meeting is shorter and less awkward when that is clear.

Have the written note ready to send immediately afterwards. Do not send it before the conversation.

Keep the letter short

A resignation letter is an administrative document, not a summary of your feelings. Three or four sentences: that you are resigning, the role, your proposed final working day, and an offer to support the handover.

No reasons. No grievances, however well-founded, and no gratitude so effusive it reads as an apology. The letter sits in a file that people you have not met will read.

If you want to say what went wrong, do it separately and verbally, to someone who can act on it, once the resignation itself is settled. Written complaints attached to a resignation harden positions on both sides.

Notice and handover

Notice periods, what an employer may require of you during them, garden leave, accrued holiday, bonus treatment and any restriction on where you work next differ enormously by country, contract and employer. Read your own contract before you name a date, and take anything that is unclear or contested to a qualified employment adviser or your national employment body rather than to a colleague.

What is not contract-specific is the handover, and it is where reputations are made. Do it in writing, unprompted:

  • A document listing what you own, its current state, and what happens if nobody touches it for a month.
  • The things that exist only in your head — the supplier who must be phoned rather than emailed, the report that breaks on the first of the month, the password that is written down in the wrong place.
  • Named handover recipients for each item, agreed with your manager rather than assumed.
  • Introductions to your external contacts, made by you, before you go.

This takes a day or two. It is the cheapest reputational investment available to anyone.

Counter-offers

Expect one if you are any good, and treat it as information rather than flattery.

A counter-offer tells you that your employer could have paid you more and was not doing so. It also tells you the money was found under pressure, which is a different thing from the money being planned.

Practitioners who watch this closely tend to report the same pattern: most people who accept a counter-offer have left anyway within a year, either because the original reason for going was never about pay, or because the relationship has quietly changed. You are now someone who was retained rather than someone who is committed, and that shows up in who gets the next stretch project.

If the money was genuinely the whole problem and the new number fixes it, accepting can be rational. Be honest about whether that is true, and be aware that you have spent whatever goodwill the resignation cost you.

A counter-offer is a company buying time to plan, priced as a compliment.

The order that matters

  • Manager first, in person, before anyone else hears it.
  • Short written note immediately after, with no reasons in it.
  • Check notice and restrictions in your own contract before naming a date.
  • Handover document written unprompted, with named recipients.
  • Referees asked, with personal contact details, while you are still an employee.

Protecting the reference

Ask for references before your last day, not after it. People are warmer while you are still in the building and much harder to reach once you are not.

Get personal email addresses and mobile numbers for three or four people: your manager, a peer from another function, someone you managed, an external contact. Ask each of them directly rather than hoping.

Also establish what the organisation itself will confirm. Many employers restrict official references to dates and job title as a matter of policy, which makes the individuals who can speak about your work considerably more important.

The last two weeks

Work them properly. The most common failure is not sabotage; it is a slow disengagement that everyone notices and nobody mentions until they are asked for a reference.

Finish what can be finished, be precise about what cannot, and be generous with your time towards whoever is picking things up. Stay off the subject of your new role in detail, and do not recruit colleagues on your way out.

On the last day, send one short note to the people you worked with most closely, with a personal email address in it. No speeches, no score-settling, nothing that reads as relief. Then leave on time.
