The employer-side of that exploitation-maneuver would be your boss telling you: "We do not have anything for you to do the next 6 weeks, starting tomorrow. You will not be paid but if you want, you can come back later."
If that happens at your company, go ahead and take your leave. If it does not happen, you may be overplaying your exploitation a little.
This happened to me. I promptly informed them that they hadn't hired me as a contractor, hand't been paying me the rates I demand as a contractor, and bid them farewell.
