Focus on the results and not on working hours!
One of the main questions of entrepreneurs is "How will I monitor the work of my employees?". Surely, it's a matter of trust in your team. You need to be patient. Let your employees manage their time themselves. If the only thing you check is the number of hours your workers spend in the office, it will not lead to any positive outcome. They may just surf the internet or social media during working hours and that's it. You should check the results your team brings to you, deadlines, and the quality of performed tasks. Believe us, your team will appreciate your trust and will treat you with the same respect!
