Hard worker or workaholic?

"...Workaholics are people who compulsively work long hours, often on the weekends, and through vacation time. They are physically addicted to work. This could mean 12-to-14-hour work days, every day. A hard worker on the other hand, does not put him or herself in this type of danger. They might stay extra hours right before a big deadline, but they don't get to a point where they neglect family, friends, and their own health, to a sometimes irreversible point. "
