Regular unemployment money (in French "chommage", in German "Arbeitslosengeld") is paid out to employees who no longer have a job, i.e. who are not employed. Or else to those who are employed on a lesser contract, for example if they used to work 100% but the company reduced their working hours and contract to 60%, then they'd be able to go to claim unemployment benefits (and must look for a new job) for the 40% they've lost.
The claim for unemployment benefits is made directly by the unemployed person, who is then required to demonstrate that they are making an effort to find a new job.
On the other hand, the Swiss government introduced special rules to cover employers and employees whose work is reduced during the ununsual circumstances of Covid. The application for such moneys is made by the employer, not by the employee.
If an employer does not have enough business, so that the employees remain employed (with unchanged contracts) but have much less work to do not be able to work at all (for example restaurant staff during the strict covid restrictions), then the employer can apply for support from the government, to bridge this difficult time.
In German, this is called "Kurzarbeit" which, literally translated, means "short work", and it is paid out by the "Arbeitslosenversicherung (ALV)". In French, this is "réduction de l’horaire de travail (RHT)". It is paid out by the "l’assurance-chômage (AC)".

For an employee, it would not be legal (and would be a lot of extra effort, for nothing) to try to claim money from the unemployment office while still fully employed.
For the employer, it would not be legal (but may be very profitable, for a dishonest employer) to claim the emergency support from the unemployment office while the employer still has work for the employee to do.
