Pros
The hours were always steady due to the nature of the business. You got to know some people very well because of their frequency in attending to donate. Not a whole lot of growth opportunity as a phlebotomist. Though new donors were the most challenging, frequent donors were easy to insert the needle because of how often they would donate. Some overtime depending on if one of the last donors were to have a reaction that would require them to remain in the chairs to hydrate and eat something. Benefits were sub-par to non existent but at least it was something rather than nothing at all.
Cons
Long hours on your feet. Some donors could be very difficult in personality and the company expected you to tolerate them unless they became overwhelmingly verbally abusive and of course physically threatening. Have to "watch" and listen to a limited repertoire of movies. Repetitive work.
