Fun!
At first, I was leaning towards:
procrastination.
A place of work, and not of play,
You know that's what the vermin say.
Procrastination is a boss's worst nightmare. I'm hearing both the voice of the boss & of the employee in these lines.
Is it this or that, the question sly,
But in the end you'll question why?
I'm not procrastinating (Really...) or, am I?
Why do I know I'll regret this.
A miracle you want to find,
And get yourself out of a bind.
Randomly searching the internet can sometimes yield great insights.
So while you're here, follow a hunch,
It may just happen before lunch.
Or, searching StackExchange :) If you're lucky, you'll be ready for a break at lunchtime.

equivocation
A place of work, and not of play,
Refers to the "vocation" in equivocation
You know that's what the vermin say.
Is it this or that, the question sly,
These lines had me thinking of Hamlet. Chief equivocator
A miracle you want to find
And get yourself out of a bind.
Those equivocating are seeking an answer to a question, fundamentally
So while you're here, follow a hunch,
It may just happen before lunch.
Just pick something already!
