Some jobs have very clear lines between when you’re “on” and when you’re “off.” But when you work in a role where the lines are blurred — or potentially nonexistent — it’s important to protect your non-work time. If you feel like work is taking over most of your waking hours, start by clearly defining what “after hours” means for you. Take into account the number of hours you’re expected to work each week, as well as personal commitments like taking your kids to school, making a certain train, or attending an exercise class you really enjoy. When do you need to start and stop to put in the appropriate amount of work time? Then, develop mental clarity about what needs to get done and when you will do it. Keep track of your tasks and plan them out. Make sure you block off time for an end-of-workday wrap-up, where you review and make sure you did everything you needed to do for the day. Lastly, communicate with your colleagues about how (or if) you want to be contacted during your off hours. Really guard your time. If you don’t, you won’t get the mental break that everyone needs.
