The key word in the definition of exploit is "full" use. To simply use something and derive a profit from it is not necessarily exploitative, as the noted comment suggests.
In the context of this thread, the original claim put forth is that being "used" for 80 hours is in fact exploitative; by one calculation, this amounts to 100% of your waking time in a standard 5 day work week, assuming a typical 8 hour daily sleep period. On the other hand, being used for a 40 hour work week is not exploitative; you still have 50% of your time remaining for non-work life. The math here is used for illustrative purposes, but a reasonable interpretation of "full" would tend towards 100%, not 50%.
Workers are truly exploited in some cases. To label a 40 hour work week as exploitation, in most cases, is simply hyperbole that diminishes the real suffering and ethical issues of actual worker exploitation.
