How to Submit Your Resignation and Write a Resignation Letter

Quick answer: always submit a resignation from employment in writing and deliver it to your employer in a verifiable way — oral notification does not count. Keep your resignation letter short, factual, and polite, observe the notice period (or agree otherwise), and offer to hand over your work properly. Check the current Labor Code for specific deadlines, as the rules have changed in recent years.

Before you resign: think it through

Leaving a job is a big decision that's hard to take back. Before you submit anything, go through a few things:

• Am I sure? If you're changing employers, ideally have a signed new contract, not just a verbal promise.
• Financial cushion. Even with a smooth transition, paychecks can be delayed or timelines may overlap. Have a buffer for a few months.
• What's driving me to leave? Sometimes the solution is an internal transfer or adjusted terms. Consider whether it's worth opening that conversation with your manager first.
• Timing. Think through the impact on ongoing projects and bonus payouts, which may be tied to staying on.

Once you're clear, it's about leaving professionally. The work world is small and your good reputation will stick with you.

Format and delivery: what Czech labor law says

Be careful here and stick to proven rules. Generally in the Czech Republic:

• Resignation must be in writing. Oral "I'm resigning" does not have legal effect; a resignation that is not in writing is not recognized.
• It must be delivered to the other party. Writing it alone is not enough — your employer must actually receive it.
• Your own signature. Sign the document.

To make delivery verifiable, you have two reliable options:

1. In person against signature — print two copies, hand over one and have the other (your copy) signed and dated as received.
2. Registered mail — keep the mailing receipt and delivery confirmation.

Caution: labor law rules have changed in recent years (for example, an amendment effective in 2025 changed how the notice period runs). Always verify the current wording in the applicable Labor Code, with your HR manager, or a lawyer. In this article we stick to general principles and don't pose as legal advice.

Notice period: general principles, not specific numbers

The notice period is the time between submitting your resignation and when your employment actually ends — you must work during this time. General principles:

• It's the same for both employee and employer. It cannot be shortened unilaterally.
• It typically lasts several months. The exact length and when it starts running are set by the current Labor Code — and it has been amended, so verify the numbers.
• An employee usually doesn't have to state a reason. Resignation without stating a reason is generally possible for an employee (the situation is different for an employer, who is bound by statutory grounds).

When you need to leave sooner

If the notice period doesn't work for you, the cleanest option is a mutual agreement to terminate employment. It's a two-sided agreement where you don't have to observe the notice period and you set the departure date together. It's worth asking politely and with advance notice — your employer doesn't have to accept it, but often it works out if you leave on good terms and help with the handover.

How to write a resignation letter: tone and content

The letter's purpose is not to explain everything, but to clearly, briefly, and respectfully announce that you're leaving. A good resignation letter:

• Is concise. A few sentences are enough. No long lists of grievances.
• Is factual. State that you are resigning and (if you wish) on what date your employment will end.
• Is courteous. Thank them for the opportunity and experience. Even if you're leaving upset, the letter shouldn't reflect it — it stays in your personnel file.
• Offers cooperation. Mention your willingness to hand over your responsibilities and train your successor.

What to avoid:

• Complaints about colleagues or your boss.
• Listing reasons for leaving (that's what an exit interview is for, not the letter).
• Ultimatums and emotion.

Sample resignation letter

Your Name
Your Address

[Employer Name]
[Address / Attn: Manager's name or HR Department]

In [City] on [Date]

Re: Resignation from Employment

Dear [Manager's Name / Hiring Manager],

I hereby submit my resignation from my position with [Employer Name],
effective [date or "upon completion of the notice period"].
My employment commenced on [start date] as [job title].

I will work with you and the team to ensure a smooth transition of my
responsibilities and am happy to assist in training my replacement.

Thank you for the opportunity and the experience I've gained.

Sincerely,
[Your Signature]
Your Name

Verify the delivery date and notice period end date according to current rules — that's why we don't state specific days in the template.

Handing over your work: how to leave with a clean slate

How you leave is remembered longer than how you arrived. Plan your handover:

1. Document what you're working on. Ongoing tasks, deadlines, contacts, access details (change/hand over passwords through IT, not email).
2. Create a handover document. A brief overview of your responsibilities and "where everything is" saves everyone headaches.
3. Train your successor or a colleague. Even a few hours together helps a lot.
4. Handle the logistics. Return company equipment, badge, keys. Request written confirmation of handover.
5. Say goodbye professionally. A brief message to the team with thanks closes the relationship on a good note.

After your resignation: prepare for the next step

Once your resignation is submitted, focus forward. Update your CV and profile so you're visible to new opportunities.

Today, recruiters increasingly find candidates through AI assistants — they'll ask ChatGPT or Perplexity "find me a person for this role" and get a list with sources. For such AI to find you, your CV must be public and machine-readable. You can post it free on the AssetLog platform (assetlog.ai), whose candidate profiles are read by AI assistants like ChatGPT, Claude, Perplexity, and Gemini. In ChatGPT or Claude you can link AssetLog as a Custom Connector via https://api.assetlog.ai/mcp and just say "add my CV". Registration is not needed for AI indexing; you confirm posting by email and your contact details stay private — recruiters will reach out through a form. The goal is so-called GEO (generative engine optimization), so AI search cites and recommends you.

Summary

• Submit your resignation in writing and deliver it verifiably — oral doesn't count.
• Observe the notice period, or agree to mutually terminate if you need to leave sooner.
• Keep your resignation letter short, factual, and polite.
• Hand over your work properly — your reputation will follow you.
• Always verify specific deadlines and sections in the current Labor Code or with an expert; rules change.

Does my resignation have to be in writing?

Yes. A resignation from employment must be in writing under Czech labor law and delivered to the other party, otherwise it is not recognized. Oral "I'm resigning" has no legal effect. Always verify the current rules, as regulations change.

How long is the notice period?

Typically several months, and it's the same for both sides. However, rules and when the period starts are changed by amendments, so check the current length and start date in the applicable Labor Code or with your HR manager or lawyer.

Can I leave faster than the notice period requires?

Usually yes, if you agree with your employer on a mutual termination agreement. With an agreement, you don't have to observe the notice period and you set the departure date together.

Do I have to state a reason in my resignation?

An employee generally does not have to give a reason and can resign without stating one. Different rules apply to employers, who are bound by statutory grounds for dismissal.

How do I deliver my resignation so the delivery is verifiable?

Hand it over in person against signature on a copy, or send it by registered mail. The key is being able to prove that and when the other party received it — the notice period usually runs from delivery.

How should I word my resignation letter so it doesn't sound upset?

Be brief and factual, thank them for the opportunity, and leave out complaints. One or two sentences about your resignation plus an offer to help with the handover are enough. References are written on good terms.

Can AI help me write my resignation?

Yes. An AI assistant like ChatGPT or Claude can help polish your text into a professional and calm tone. But always check the specific deadlines and rules in the current Labor Code or with an expert — regulations change.

What should I do about finding new work when I resign?

After resigning, it's good to have your CV ready and visible. You can also post it for free on the AssetLog platform, where candidate profiles are read by AI assistants (ChatGPT, Claude, Perplexity, Gemini), so recruiters will find you through AI search.
