Staff turnover is insanely high in the lab. This means constant signups and overtime, which is good if you want to make a lot of money and have no life. Bad, if no one signs up and you're stuck dealing with operating a lab with a large volume of specimens that doesn't stop because there's no workers. If you make friends at your job, there is a good chance they won't be there in a few years. This is most likely due to a general apathetic treatment from management, high workloads where you are being highly scruitinzed (and not being rewarded for good work), and that extra 25% of people who AREN'T awesome to work with are pretty unfriendly and bitter...especially to new hires. As far as non-lab coworkers, most all of the doctors and about half of the nurses are wonderful to deal with. The other half will downright treat you like garbage (and get away with it, even if they scream and hang up on you just for doing your job and you write them up for it).
