Yes! It is also important to have an employment contract in writing.
You must have one in your possession by the time you start work.
Your contract is created in duplicate: one for you and one for your employer, Randstad. This kind of student contract is always for a limited period and ends on the expiry date.
You are also required to get a copy of the work regulations, for which you will sign a proof of receipt.
At Randstad it is possible to sign your employment contracts electronically. You can read how to do that here
Maybe, but it must be stated in your contract.
Working as a temping student? Then you will generally receive your contracts for a 1-week period. In the case of temping, the trial period is generally 3 days. During this trial period either party is entitled to cancel the employment contract without notice or compensation.
Do you have a contract for a specific period? Then the trial period related to student employment is a minimum of 7 and maximum of 14 days. Moreover, neither you nor your employer are entitled to terminate the employment contract during the first 7 days. As from the 8th to the 14th day you or your employer may terminate the contract without notice or compensation.
