In the DP A1 form, you must outline that the duration of the posting must not exceed twenty-four months.
In case of more than twenty-four months posting, as an employer, you can propose to your posted employee to join the social security system of the host country.
Or if a mutual agreement exists between your country and the host country, the entity issuing the DP A1 form can extend the validity of the document so that your employee continues to have access to social security coverage.
A clear legal setting has been set up by the European Union for the posting of workers with each country being responsible for implementing it into their own judicial system.
Thus, if you decide to post worker to one of the European Union countries, the procedures are different according to the country of destination as well as the duration and objective of the mission.
