Duffy's "Doing The Dirty Work"

I've worked as a porter in Manhattan for the last 3 summers, and don't believe it defines me as who I am. It requires a lot of physical labor and cleaning which is not what I want to do, but without work there's no money. So i basically think just cause you work as something doesn't mean it defines who you are unless that's what your passionate about doing. Where i work they are usually immigrants that can barely speak English and are non union workers. In Duffy's "Doing The Dirty Work" states,  "To cut costs,building owners and managers have increasingly subcontracted out cleaning work to cleaning services as opposed to hiring employees with access to benefits and higher levels of protection"(122). The cleaning companies hire people and they before they can get in the union and have protection to keep their job, they get fired and the next guy comes in. They do this so that they can save money and use the workers without them being protected by the union.
