Perks I would give on a company

If I owned a company, it would probably be related to music, maybe I would produce music. The perk I would give to my employees would be the following:

• I would allow my employees to work the time they want, whenever they want. On the other hand, I don't want them to slack off, my conditions would be that they have to keep up with their work in time and with excellent quality. There would be zero tolerance for slackers.

Essentially I want my workers to be happy, with that perk only they would be allowed to do whatever they want, always they don't slack off.
