I have a manager who is absolutely great. You name it he's got what you want in a boss. He works incredibly long hours though. Typically 6-7 days a week, during the week at least 10 hour days and often late into the night, say work 10-7 then again from 9-11, sometimes he works till 4 or 5am then is back at work the next morning. Weekends he often is working at least 5 hours a day.
Normally I wouldn't care too much about his work schedule, if he wants to work its up to him. However, he's told me that in the past he's been hospitalized due to a heart problem from overwork and stress, and he also said in an offhand way working so many hours is damaging his marriage and relationship with his kids.
Couple notes on specifics:
1.) A large portion of his work is triaging defects, clarifying requirements, and orchestrating the api's between in a large system. Our team manages a vital service in the overall scheme of things.
2.) Often times he doesn't want to work, but people pull him into discussions when problems arise or they need his input. His boss is very demanding and expects him to respond quickly when asked.
3.) I'm a relative junior to the team so I can help him solve problems, in our service but when it comes to the intersystem problems I don't yet have experience enough to competently fill in for him, particularly when there's an outage and people are scrambling to fix things.
4.) He pulls people from our team as needed to fix problems, but works alongside us as we work.
5.) He's happy with my performance.
6.) Budget is too tight to hire someone else, our team size is around 10 dev, qa, and architect all counted.
I'm really afraid something bad will happen to him, another heart attack, or divorce or he just gets tired of it all and quits. Is there anything an employee can do to help an overworked boss?
