Posting notification in the Czech Republic: step by step

A German engineering firm sends three technicians to a machine installation in Ostrava for six weeks. The site manager assumes the service contract with the Czech client covers everything. It does not: before the first technician sets foot on the site, the posting has to be notified to the Czech labour authority, and that notification carries its own binding deadline.

Posting notification is a filing made to the regional labour office before a posted worker begins work in the Czech Republic, governed by Czech employment legislation implementing the EU posting-of-workers framework. It must reach the authority before the first working day, not on it and not after it, and it identifies the sending employer, the worker, the Czech workplace, and the expected duration of the assignment.

This page sets out who files, what deadline binds the filing, what the file has to contain, and where an owner sending staff into the Czech Republic for the first time typically loses time.

When does posting notification apply in the Czech Republic?

Posting notification applies whenever an employer established outside the Czech Republic sends an employee to perform work on Czech territory for a temporary period – at a Czech client, at a group company, or at its own Czech branch. The duty is triggered by where the work is actually carried out, not by where the contract was signed.

The employer stays legally the employer of record abroad; the posting does not create a Czech employment relationship. What changes is the place of performance, and Czech law attaches a notification duty to that change regardless of how long the assignment lasts. A posting of a single day counts; a posting of a year counts under the same rule.

Business travel that involves no actual work performance in the Czech Republic – a negotiation, a conference, a site inspection without hands-on tasks – does not trigger the duty. The line runs on whether work, in the ordinary sense of performing tasks under instruction, takes place on Czech ground.

Repeated short postings to the same Czech site can be read together as one continuous assignment rather than as separate short trips, particularly where the same worker rotates in and out of the same role. The classification follows the pattern of postings, not the length of any single trip taken in isolation.

The duty is the same whether the sending employer sits inside or outside the European Union, though the immigration and permit questions that run alongside it differ and are addressed separately from the notification itself.

What conditions trigger the duty to notify?

Three conditions have to be met together: an employment relationship that continues to exist abroad during the posting, work actually performed on Czech territory, and a temporary – not permanent – character of the assignment. Where any of the three is missing, the filing is not a posting notification in the technical sense, even if the paperwork looks similar.

The duty attaches irrespective of the underlying commercial arrangement. It reaches secondments inside a corporate group, assignments made through a staffing or agency arrangement, and direct postings to a Czech-based client under a service contract. It does not depend on the value of the underlying contract, and it is not waived because the posted worker holds a senior role.

A related duty follows the same territorial logic in whistleblowing investigations conducted in a Czech workplace: the trigger there is also where the conduct or the work occurs, not where the parent company is registered.

The notification is about the place of work, not about the passport of the worker or the seat of the employer.

A posting that starts without notification cannot correct the gap afterward – the missed window cannot be restored, and it is precisely the kind of gap a labour inspection is built to find. LISTINA prepares the factual record of a posting – the notification data, the supporting documents, and the timeline – for the employer to file or to hand to a collaborating advocate, delivered within a stated number of working days.

What is the route, and what deadline binds it?

The route runs in four steps: identify the labour office with territorial jurisdiction over the place of work, assemble the data set the filing requires, file before the posted worker's first working day, and keep the confirmation of filing for the duration of the assignment. Any material change – a new workplace, an extended duration, a different posted worker – has to be reported without delay once it occurs.

• Identify the labour office with jurisdiction over the actual place of work.
• Assemble the notification data set before the assignment starts.
• File the notification before the first working day – not on it, not after it.
• Keep the confirmation of filing accessible for the duration of the posting.
• Report any material change to the assignment without delay.

The deadline is the single point that carries consequence. A late filing does not just risk a fine – it closes the route to treating the posting as compliant from day one, and that starting position cannot be rebuilt after the fact. A labour inspection tests the filing against the date work actually began, not against the date the employer intended to file.

• Single short posting, no prior filing → file before the first working day → the sending employer or its Czech-based representative acts → deadline: before work starts.
• Posting already running, workplace changes → update the existing filing → the same party that filed originally → deadline: without delay upon the change.
• Posting through an agency chain → each employer in the chain checks its own filing duty → the party that is the actual employer of record acts → deadline: before that worker's first working day.

What must the file contain before filing?

The file has to identify the employer, the worker, and the work itself in terms the labour office can verify: who is sending whom, where, and for how long. Missing or inconsistent data is the most common reason a filing is bounced back for correction, and correction takes time the deadline does not extend.

• Identification of the posting employer, including its seat abroad.
• Identification of the posted worker and the position performed.
• The exact address of the Czech workplace.
• The expected start date and duration of the posting.
• A description of the work to be performed.
• A Czech-based contact person able to answer the labour office's questions.

A gap that surfaces most often concerns liability inside the posting relationship: who answers for damage caused during the assignment, and to whom. That question is decided by a different set of documents than the notification itself, and it is addressed separately in the note on employee liability, damage, and consultation with the union.

A file that is complete on paper still fails if the workplace address does not match where the worker in fact reports each morning.

An incomplete file that gets filed anyway does not stop the clock – it starts a correction cycle while the deadline keeps running. LISTINA assembles the documentary file behind a posting notification – employer and worker identification, workplace and duration data, the supporting contract chain – so the filing goes in complete the first time, delivered within a stated number of working days.

Act, wait, or stop?

Act now when the posting is clear – a defined worker, a defined Czech workplace, a defined duration – and the first working day already has a date. Wait, and check again, when the assignment might not amount to work performance at all, such as a negotiation trip with no hands-on tasks. Stop and get the classification checked before filing when a subcontractor chain makes it unclear which entity is the actual employer of record, or when the same worker has already been notified once under a different employer's name.

The register keeps the entry once a notification is filed and does not remove it because circumstances later change; corrections are made by supplementary filings, not by deleting the original one. Personal liability for the accuracy of the filing sits with the employer's statutory representative, not with the Czech client or the staffing intermediary that arranged the assignment.

Documents and registers show whether a notification was filed and what it stated. They do not show, in advance, how a labour inspection will classify a borderline case, nor whether a chain of subcontractors will be read as one posting or several. That judgment is made case by case, and it is made after the fact.

An Austrian contractor avoided a labour-inspection fine after the notification data was corrected before the first inspection visit reached the site (autumn 2025). A Hungarian subcontractor found that the labour office had already logged the same worker under a different employer's name, delaying invoicing on the underlying contract by several weeks; the pattern is common enough to warrant a separate jurisdiction note on Hungary for staffing chains that run through that market.

Frequently asked questions

When is posting notification the wrong step?

It is the wrong step when no work is actually performed in the Czech Republic – a business meeting, a negotiation, or a site visit without hands-on tasks does not trigger the duty, and filing a notification for it protects nothing. It is also the wrong step when the relationship is not a posting at all but a genuine Czech employment contract, which follows a different route entirely.

What is the alternative?

Where the assignment amounts to a local hire rather than a temporary posting, the correct route is a Czech employment contract and the registrations that follow from it, not a posting notification. Where the trip involves no work performance, no filing of any kind is required.

What stops the clock?

Nothing stops the clock once the posting's first working day is fixed; the notification has to be filed before that date regardless of pending negotiations, contract signature delays, or internal approvals. Only an actual postponement of the start date moves the deadline, and it moves with it – it does not pause it.

What is enforceable afterwards?

A filed and confirmed notification is what a labour inspection checks against; it is the record that the assignment was disclosed before it started. It does not itself create rights between the employer and the worker – those follow from the employment contract and from Czech law on posted workers' minimum terms, which sit alongside the notification, not inside it.
