Can I take a second job in Czechia?
Yes — and in a different field you ask nobody. The Labour Code restricts one thing only: gainful activity identical to your employer's business scope. For that you need their prior written consent under § 304 — and they may revoke it in writing at any time, after which you must stop without undue delay. A waiter may code in the evenings; a developer may not code for a competitor without consent. Always free: scientific, teaching, journalistic, literary and artistic work. There is no duty to notify: you report a second job nowhere. With the same employer, a second relationship works only for a different type of work — and § 304 covers agreements too, DPP included.
📋 The rules
- Different field: no consent, no notification
- Employer's own field: prior written consent (§ 304)
- Consent is revocable in writing — you must then stop
- Always free: science, teaching, journalism, literature, art
- Same employer: second contract only for a different work type
🔓 Exceptions
- Post-employment non-compete clauses: a separate contract (mandatory financial compensation)
- Civil servants: stricter special regimes
- Scientific, teaching, journalistic, literary and artistic work: always free, no consent required
⚠️ Penalties & fines
There is no criminal or administrative dimension — the consequences are labour-law ones, but they bite. Gainful activity in the employer's field without written consent breaches a statutory duty: it starts with a written reprimand and, where the breach is serious, can end in dismissal under § 52(g), in extreme cases immediate termination. If the employer suffers provable harm, they can claim damages on top of ending the employment. A post-employment non-compete clause is a separate contractual matter — without financial compensation it is not valid at all.

❓ Frequently asked
Must I report a second job?
No — the Labour Code knows no notification duty and your boss has no right to demand one. Consent is needed only where your gainful activity matches the employer's business scope, and it must be written and given in advance.
What exactly is a "matching field"?
What counts is the employer's registered business scope, not your job title or department. An accountant at an engineering firm needs consent for outside bookkeeping only if the firm itself offers accounting services to clients.
Can the boss revoke consent?
Yes, in writing and with reasons — consent is not irreversible and can be withdrawn at any point. Once revoked, you must end the competing activity without undue delay, or you breach your duties, with consequences up to dismissal.
Does § 304 cover casual DPP work?
Yes — it applies to all basic employment relationships, agreements to perform work and to work activity included. Neither the form nor the size of the contract releases you from obtaining consent, not even for a few hours a month.
What if I want a second job with the same employer?
Then a different condition applies: a second relationship with the same firm is possible only for a different type of work. The same work on two contracts is not allowed, not even via an agreement — the limits can't be circumvented.
