In my past job as an Office Manager for a boutique interior design firm, we didn't have the budget for a cleaning service, so it fell to me to sweep and mop the floor. When I worked for a restoration company in their retail store, I had frequent arguments with my supervisor over how many times I could sweep the floor and still remain cost effective (he insisted it was always once more).

I HATE sweeping floors.

So I went back to college and got a diploma in Mechanical Engineering (Robotics & Automation) to make myself more valuable. I am currently employed as a Weld Technician and my job is to respond to robot breakdowns in the plant and fix the systems.

Oh, and when I'm not busy, my boss expects me to sweep the floor.

If it's not in my job description, can they just tack that on under 'other duties as assigned'? Where does that end (either theoretically or as a practical legal matter)? Can they have me filing our quarterly financial statements and picking up the boss' dry cleaning just 'cause they feel like it?
