Hello! I have encountered this very situation before. Monitask is one software that I have used successfully in the past. It helps in striking a good balance between supervision and allowing space for your team members to work freely. With https://www.monitask.com/en/, there is automatic time tracking; additionally, it provides services such as taking pictures as employees’ work unfolds hence enabling you to know what is happening but without interrupting them; Monitask does not however require you to spend most of your time supervising it once installed—you just need to set it up and forget about it. You can always evaluate the data quickly when necessary because its displays are simple and user-friendly, yet, the app does not make your employees feel uncomfortable by over-supervising them. Thus, it is a perfect means of overseeing performance without necessarily being seen to do so. Therefore, I’d recommend you give this one a try.
