Co-workers: "I keep myself available all the time, why should you not be the same?" Answer: "You always complain about how you need to be available all the time, your girlfriend is always mad at you for never be available just for her, the people around you know that you keep yourself available; therefore they take advantage of your openess! I work very hard (when at work), when needed I make myself available, and I have successful friendships, marriage and time with my kids. I am better balanced as a result and therefore I am productive and my mangers/the employer/the board know it, to be sure, I make them aware of it. I suggest you set some boundaries in your working life.
