Business trips
Project work and hands-on tasks abroad can trigger one. Attending a conference usually doesn't, but presenting, training or delivering client work there can, sometimes from day one.
European authorities are drastically intensifying inspections of cross border assignments. WorkFlex evaluates every trip request, handles necessary posted worker notifications (PWNs) automatically, and robustly protects your business.

It applies to service work in another EU or EEA country.
It depends: not every trip abroad needs one. Whether one is due comes down to the destination, the activity and the duration, and each country sets its own rules. WorkFlex checks every trip and files only where it's actually required.

Belgium is the only country that treats a work-from-anywhere trip as a posting, and can require a notification before even a short remote stay.
Longer postings need one matching the assignment's dates and place of work.
Construction, assembly and installation are checked closely, often with extra documents.
Who files it? The employer files the notification in the host country, before departure, through that country's own portal. Employees cannot do it themselves. WorkFlex files it automatically. Read the compliance deep dive.
Missing notifications are not a formality. Labour inspectors across the EU check for them on site, and the penalties fall on the employer.
Inspectors can halt the work or remove your team from site. For example France, Austria and Belgium run frequent checks at building sites, trade shows and client offices.
Penalties are charged per employee and per country, running into the thousands, with France and Austria among the strictest.
The client can be held jointly liable, and a stopped project or a public breach puts the business relationship and your reputation at risk.
WorkFlex's engine adapts posted worker notifications to country-specific requirements based on your business traveller's destination. No more headaches from manually following each country's unique requirements.
