Notice period confusion after Czech Labour Code flexi-amendment (June 2025) — can employer apply old contract wording?
​
Hi everyone, looking for clarity on a notice period situation in Czech Republic.
My situation
I joined a company in prague in April 2025 and submitted my resignation on 14 May 2026 with a 2-month notice period.
What my contract says
The notice period starts on the 1st of the month following delivery of resignation — so under this wording my last day would be 31 July 2026.
What HR is saying
HR claims the new June 2025 flexi-amendment only applies to employees who signed an internal company amendment. Since I didn't, old rules apply to me.
The actual issue
The flexi-amendment (effective 1 June 2025) changed Section 51(1) — notice now starts from day of delivery, which would make my last day 14 July 2026. However, the new law also allows parties to contractually agree their own start date — so since my contract already has the old wording, it might legally prevail anyway.
HR's reasoning seems wrong, but their conclusion might accidentally be correct due to the contract wording.
Has anyone dealt with this or knows how it's being interpreted in practice? 🙏
