1. Can I attend the pre-departure briefing while I am still employed by my current employer?

Yes, according to Belgian legislation you can combine two employment contracts simultaneously.

We even recommend staying under a contract with your current employer as long as possible because the administrative procedures for obtaining a work permit in the country of assignment can be lengthy. So, you can only be 100 % sure of the date of your departure when you have received the ‘fiat’ of the country.

For you to attend the 2-week pre-departure briefing on a full-time basis, we advise you to take (paid or unpaid) leave with your employer for that term.
