Quick Answer

Posting a worker to another EU country keeps them formally employed under the sending country's law, but the Posting of Workers Directive (96/71/EC, as amended by 2018/957/EU) requires the host country's 'hard core' terms — pay, working time, safety, and more — to apply during the posting. Social security generally stays with the home country via an A1 certificate. Specific requirements vary by country and require legal review.

Typical first step
Confirm the posting qualifies as a genuine posting, not disguised local employment

Your Options

Post under the standard framework

For a genuine, temporary posting, home-country employment continues alongside host-country hard-core terms.

Apply for an A1 certificate

Confirms which country's social security system covers the posted worker during the posting.

Check host-country notification requirements

Many countries require advance notification or registration of posted workers — requirements vary significantly.

Steps to Take

  1. 1

    Confirm the posting is genuine

    A temporary assignment with an ongoing employment relationship with the sending employer, not a disguised local hire.

  2. 2

    Identify the host country's hard-core terms

    Pay, working time, holidays, and safety rules that must apply during the posting.

  3. 3

    Apply for an A1 certificate

    To confirm continued home-country social security coverage.

  4. 4

    Meet any host-country notification/registration requirements

    Vary significantly by country — some have detailed advance-notification systems.

  5. 5

    Get country-specific legal advice

    Both the sending and host country's specific rules need checking — this is a genuinely two-sided compliance question.

Documents You May Need

  • Employment contract with the sending employer
  • A1 certificate (or application for one)
  • Posting assignment letter/documentation
  • Proof of host-country notification, where required
  • Pay and working-time records for the posting period

Common Mistakes to Avoid

  • Treating a long-term or repeated assignment as a short posting
  • Not obtaining an A1 certificate before the posting begins
  • Overlooking host-country notification requirements
  • Applying only home-country pay/terms without host-country hard-core terms

Risks & Deadlines

Posting duration limits can change the legal treatment

Requires legal review for the specific circumstances — a posting that runs too long, or is effectively repeated indefinitely, can lose its 'posting' status and trigger different rules.

Notification requirements and deadlines vary widely

Requires legal review for the specific host country — some countries require notification before the posting starts, with penalties for missing it.

Estimated Costs

  • A1 certificate application: Typically free, but requires legal review for the specific process
  • Host-country notification/registration, where required: Requires legal review — varies by country
  • Initial lawyer/compliance consultation: Varies by lawyer and country — ask for a quote upfront

When to Contact a Lawyer

  • You're unsure whether an assignment qualifies as a genuine posting
  • The posting is likely to run long, or be repeated
  • You're unsure what the host country's hard-core terms actually require
  • There's a dispute over pay or working conditions during a posting

Frequently asked questions

Generally no — with a valid A1 certificate, social security generally stays with the home country during the posting, avoiding double contributions.

Not necessarily identical, but the host country's pay rules (including any applicable collective agreements) are part of the hard-core terms that must be respected during the posting.

There are rules affecting long or repeated postings, and exceeding certain thresholds can change the legal treatment — the specifics depend on the situation and need legal review.
