Story of my life in the office

I work my ass off and get the job done, almost 4 to 5 hours before my shift ends. And then I casually sit with other colleagues and chat a bit.
And my boss comes in and says you have no work ethics and are lazy.

And i'm like you fucker I got my job done, why can't you see that. I doesn't mean that my job is easy if I get it done before time. I just means that i'm more fucking efficient then the other employees.While the other employees were gossiping, I was on my desk working. Why can't that fucker see that.

Not to mention as I get my job done before time, I get burdened with other people's work, coz apparently they are overloaded with work.
Fucking idiocracy.
