I disagree entirely. Indeed I find the suggestion that your employer owns the fruits of all your free time to be absolutely asinine.

Employees aren't indentured servants. Full time, salaried employment in the United States is de facto 40 hours. If you work less than that (without prior agreement), you can expect repercussions. If you work more than that, you can expect... nothing. Ergo what is being purchased under a full-time agreement is clearly the customary amount of work. Anything beyond that is being done so at the beneficence of the employee (or more likely as part of a long-term strategic play). In any case, it is the very definition of "above and beyond the call of duty".
