On-call contract
The pitfall of an on-call contract is that, over time, the employee may claim a minimum number of hours at which s/he is actually performing work for his/her employer. The judge will look at the average number of hours that the employee has actually been performing work for the employer during the previous three months. An on-call contract then quickly becomes an employment agreement for an indefinite period of time, which may not be easy to dissolve without a struggle. If this is not what you want, there needs to be express agreement about the duration of the contract and about a trial period, if any.
