- Almost no career prospects of a long term or permanent position. Most of very good engineers need to leave CERN, and the departments loose their expertise and knowledge.
- Too many people are on limited duration contracts up to 35/40 years old.
- Working overtime almost every day. Not good work/life balance.
- Due to the diplomatic type of permit provided, people that have built their life and family in the area have to leave the country the day after the contract ends.
