Why might I work outside contract hours?

There's a unison with it because unlike everybody having their normal 09:00 to 05:00, I pretty much carry work with me every single time there's an issue, every single time there's a need, if you get what I mean. So you might see me working late hours, you can see working on weekends, but as long as there's a need for an issue to be solved or a user, from my perspective that needs to be satisfied, work is there.
