Of course they are exploited. If I knew your philosophical leanings I could construct an example that would be quite common -- but for all I know you think it is not exploitation to offer jobs for minimum wage with no benefits that offer only 19 hrs a week of work (no benefits) but demand 24/7 availability. So let me use a more extreme example. When individuals are suspected (NOT yet proven) of illegal immigration they are sent to a detention facility. There they are not allowed amenities like fresh socks or telephone calls unless they work for them at the rate of $0.13/hr. This is happening today to many thousands of people (http://www.npr.org/2015/07/23/425511981/at-low-pay-government-hires-immigrants-held-at-detention-centers http://www.npr.org/2015/07/23/425511981/at-low-pay-governmen...). Surely THAT counts as exploitation.
