The bottom line.... Time tracking is a pain, but there are many benefits. You don't have to track every single moment of the day to get measurable results. Strive for capturing at least 80% of the workday. When you implement the new time tracking policy, speak to your employees in terms of the benefits they'll see, like keeping their risk of burn out at a minimum. Also, a better bottom line for the business means more opportunity for bonuses and salary increases. The whole company should benefit from better performance.
