The temporary work contract is signed with an employed person by the temporary work agency. A person employed on this kind of contract has the same right and benefits like a person on the “typical” contract of employment. The main difference is in the notice period as well as the fact that holiday leave is calculated in the amount of 2 days after working every 30 days.
Remember that the agency can direct you for a temporary job to a specific employer for no longer period than the maximum 18 months during 36 calendar months. It simply means that you cannot work for the same employer for more than 18 months within 3 years.
