When work controls your life

am i the only one who feels as if work controls my entire life? As a clinical/tech support person for a large university hospital, I am always on call. I didn't realize that this was part and parcel of the job when I first signed up. This means that when i am away on vacation, on weekends, I am tied to a pager and cell phone. I have been interrupted at church, on dates, during concerts etc., How did this happen? Good question.
