Swiss law does not set a minimum wage. Some collective working agreements or standard employment contracts provide for minimum wages for certain types of profession. The employer and employee agree the wage level when the employee is taken on.
If you are prevented from working through no fault of your own, such as illness, an accident, military service etc., the law prescribes that the employer must continue to pay the wage for a limited time. The length of time for which this happens depends on the duration of the employment contract, but the obligation to continue paying the wage does not apply if an employment contract is for less than three months.
