Being able to separate your personal and work life is important. When your identity and sense of self worth gets coupled to your current employment it leads to unhealthy behaviors that are difficult to correct. I’ve experienced this personally before and it’s not an experience I ever intend to repeat. Even when I would physically leave work my mind was still there, rehashing the events that made me thoroughly miserable. These days I don’t have work slack or email on my phone, and every Friday I completely power off my work laptop. As someone who has difficulty disconnecting, being able to establish firm boundaries with work has done wonders for my mental health.
