Vantaggi
Regular meetings with management, If there was a problem with my performance I generally knew about it fairly quick. Once you're used to it, the work itself becomes second nature and you can do it with your headphones in. They have a program so that you can take classes for free and get certified as a lab animal technician and move into a better-paying and more comfortable career path. I went another way because I had a degree beforehand, but this program seemed really cool and the guy that teaches it is nice.
Svantaggi
The workrooms are hot and loud, the work is difficult, and the staff is unpredictable- you might have great coworkers, or they might be really weird and aggressive, and you'll probably get moved around a lot regardless. High turnover means you'll get full time pretty quick if you start as a temp. The environment can be cliquey and you definitely want to be friendly with the floor supervisors. Doesn't pay amazing but there's basically no barrier to entry and they're pretty much always hiring.
