Hello Jacques-Alexandre Hallé,

Thank you for reaching out to us.

If you set your service to be 60 minutes long in service/edit service time slot for that service will be one hour long.

If you thought that employee in total should work all 3 services for an hour a day, Amelia doesn't have those exact settings.

The only thing you can do is to set the employee's working hours to work one hour a day.

I'll kindly ask you to add it as a feature suggestion on this link https://features.wpamelia.com/

Features are pushed up on our "to-do" list when there are a lot of customers requesting those features, so having your vote as a customer can be beneficial to this feature being developed sooner.

We wish you all the best.

Have a nice day.
