How much notice should I give?
Two weeks is the standard in most roles and industries. Senior leadership, specialized technical, or contracted positions may require four weeks or longer — always check your contract. Anything less than two weeks risks references and rehire eligibility.
Should I explain why I'm leaving?
You're not obligated to. A simple 'pursuing a new opportunity' or 'for personal reasons' is enough in writing. Save honest feedback — if you choose to share it — for an exit interview, where it has more impact and less permanence.
What if I'm leaving on bad terms?
Especially then, keep the letter clean and gracious. The letter outlives your feelings. Future employers may verify employment, and a professional exit protects your reputation regardless of how the role actually went.
Can I resign by email?
Only as a last resort. Always tell your manager in person or on video first. The letter is documentation, not the conversation. Email-only resignations read as cold and often damage references.
Do I have to give two weeks?
Legally, in at-will employment, no. Practically, yes — leaving without notice tanks references and may forfeit unused PTO or bonuses. Unless the workplace is unsafe or hostile, the two weeks pays itself back.
Should I mention where I'm going next?
Generally no. It invites comparisons, awkward questions, and sometimes counter-offers you don't want. If your manager asks directly, you can share — but the letter itself should stay forward-looking and brief.
