1- Senior leaders need to set an example and develop a culture of life/work balance as opposed to workaholism.
2- Focus on outcomes at work as opposed to how many hours you put in. 
3.-Stop rewarding people for how many hours they put in at work. Keep a record of what you do all day for a week and you will see that a lot of time involved in workaholic activities can be reduced.
4 Chart activities you enjoy and  can engage in instead of working all the time. 
5- Learn to let go of things that can’t be controlled and control what you can which will give you more time in the day to engage in activities you enjoy.
6- Use self-talk to stop over identification with work.
7- If you create an environment where employees are appreciated and feel  included, they will be more motivated to participate, share their talents and skills and reduce your workload.
