To add on

There are supposed to be a few coming trips to taiwan next year, that i really want to go. I believe it could be one of the reasons i'm working so hard. But i most probably won't be able to go anyways, cause there's no one to cover me. So says the sgt who Knows i'm working hard.

So what's the point of working so hard, even though i'm getting $520 like the others?

I seriously don't see the point.
Do you?
