It's an ordinary office with normal workers, at least, that's all it appears to be. Scratch the surface and you'll find terrified people, petrified of making a mistake. A small mistake gets them a minor punishment. A large one results in their being changed. Each worker is given a small collar, tricked into wearing them by their boss. The collars can never be removed and gives the boss the power to change them into the furry of his choice.
Once the collar is on they can never leave the company, never talk about what goes on and can never resist the change he forces on them.
The boss is even 'fair' about it. Please him enough and he'll change you back into a human.
Now, I know this plot needs to be fleshed out a bit. I have the concept not the real plot
