The short answer
For an indefinite contract, the ordinary employee notice period is one calendar month, unless a valid contractual or CAO arrangement changes it. A fixed-term contract may not allow ordinary early resignation.
Find the termination rule that applies to you
Probation and some agency arrangements follow different rules. Read the clause before promising a new employer a start date.
Confirm the final date and money in writing
Send a clear dated resignation only once you understand the consequences. Request confirmation of the employment end date and final settlement, including leave and holiday allowance. Check accommodation and insurance separately. Resigning can affect unemployment benefits, so seek advice first if you expect to need income support or if you are ill.
What to do next
- Check contract duration, probation, notice and any interim termination clause.
- Agree a realistic new-job start date after checking the old obligations.
- Keep written confirmation and review the final settlement.
Under an ordinary one-calendar-month rule, notice received during April usually leads to an end date at the end of May, not automatically four weeks after your email. Check any different valid agreement.
Questions people ask
Is one month always the correct notice?
No. Contract type, probation and valid CAO or contract provisions can change the rule.
Can I resign from a temporary contract early?
Check whether early termination is permitted and on what terms. An agreed fixed end date does not automatically allow ordinary early notice.
Do I need proof the employer received my notice?
Yes, keep a dated written record and confirmation of receipt and the agreed final date.
Will I receive unemployment benefit after resigning?
Do not assume so. Voluntary resignation can affect WW entitlement; obtain individual advice before acting.
Can I leave while sick?
Seek advice before resigning or agreeing to termination while ill, because wages and benefit rights can be affected.
