You've decided to leave. The reasons are clear in your head, and you've already started imagining life at the next company. But between deciding to resign and actually walking out the door, there's a sequence of steps that determines whether you leave with your professional reputation intact or spend the next year explaining what happened to reference checkers.
Before you say a word to anyone
The first rule of resigning is that you don't talk about resigning until you're ready to resign. Not to your work friend. Not to the colleague you trust. Not in a Slack DM you assume is private. The moment you tell one person at your current company, assume everyone knows. Information travels at the speed of gossip, and even well-meaning colleagues share things they shouldn't.
Before your resignation conversation, three things need to be in order. You have a written offer from your next employer (not a verbal promise, a written offer with salary, start date, and terms). You've reviewed your current employment agreement for notice period requirements, non-compete clauses, and any vesting schedules for equity or retirement contributions. And you've mentally prepared your response for the counteroffer that may come, because it probably will.
The counteroffer question
About half of employees who resign receive a counteroffer. Most career advisors tell you to reject it automatically. That's too simple.
The reason to be skeptical of counteroffers is real: if the company only valued you enough to pay more or change your role after you threatened to leave, what does that say about how they'll treat you going forward? Research consistently shows that a significant portion of employees who accept counteroffers leave within 12 months anyway, either because the underlying issues remain or because the relationship dynamic shifts.
But sometimes the counteroffer addresses a legitimate problem. If you were underpaid and the company corrects it meaningfully (not just 5% that should have come in your last raise), and the reason you were leaving was primarily financial, it's worth considering. Just know that accepting a counteroffer changes things. Your loyalty will be quietly questioned. Future opportunities may flow to employees perceived as "committed."
Decide before the conversation happens. If you walk into the resignation meeting open to a counteroffer, you'll be negotiating on the spot with impaired judgment. Make the decision in advance and stick to it.
The resignation conversation
This happens in person (or video, if remote). Not email. Not Slack. Not a letter left on your manager's desk. You owe your direct supervisor the respect of a face-to-face conversation, even if the relationship is strained.
Keep it short. "I wanted to let you know that I've accepted a position at another company, and my last day will be [date]." That's the entire opening. You don't need to explain why in detail. You don't need to justify your decision. You especially don't need to list grievances. The resignation meeting is not an exit interview.
According to BLS data, millions of Americans leave their jobs every month. This is a normal professional event, not a personal betrayal. Treat it accordingly.
The standard notice period is two weeks. Check your employment agreement because some roles (particularly management and client-facing positions) require more. If your contract says 30 days, give 30 days. Giving less than what's required burns the bridge, period.
The two weeks that matter most
Your final two weeks at a company shape how people remember you more than the two years that preceded them. This is unfair. It's also true.
During your notice period, document everything your replacement will need. Current project status, key contacts, login credentials (for shared tools, not personal accounts), recurring deadlines, and any institutional knowledge that lives only in your head. Do this proactively without being asked. Create a transition document and share it with your manager and whoever is inheriting your work.
Resist the temptation to check out early. The impulse to coast through your final days is natural, especially if you're excited about the new role. But every interaction during your notice period is a final impression. The colleagues who watch you phone it in for two weeks will remember that longer than the great work you did in the previous two years.
Finish what you can. Hand off what you can't with clear instructions. Be available for questions. That's the standard. Meeting it costs you nothing and leaving below it costs you references.
The resignation letter
After the verbal conversation, send a formal resignation letter (email is fine). Keep it to four sentences maximum.
State that you're resigning. State your last day. Thank them for the opportunity (even if you're leaving because the opportunity was terrible). Offer to help with the transition during your remaining time. That's it. No explanations. No feedback. No passive-aggressive commentary about what the company could do better. The resignation letter is a professional document that goes into your HR file. Write it like you know your next employer might somehow read it.
After you leave
Update your LinkedIn on your first day at the new company, not before. Premature updates invite awkward conversations during your notice period. Connect with the colleagues you want to stay in touch with, but don't mass-invite your entire former team the day you leave. That feels transactional.
If your former employer asks you to complete an exit interview, be constructive but measured. The things you say in an exit interview rarely change company policy, but they can absolutely follow you in industry circles. Share process feedback if asked. Skip the personal grievances. "The workload became unsustainable and I wasn't able to resolve it through the channels available to me" lands better than a list of complaints about your manager.
Before you submit your resignation, write out your counteroffer decision, confirm your notice period, and draft your four-sentence resignation letter. Walk in prepared. Walk out professional. The sequence matters more than any individual step.
