Pros

You Meet Some Nice People

Cons

Back Stabbing Liars who only look out for them selves, this Company does not care about their employees or the Patients, they only care about Metrics and MONEY. they will work their Lab Techs into the ground with barely any staff, then wonder why their turn around times are so bad. They are inefficient with supplies, and help the turn over rate is ridiculous, and forget about being trained properly Figure it out for your self, then when you do something wrong THATS YOUR FAULT!! They only promote or believe in the Brown Nosers who have no Company Loyalty and would leave if given a better job offer in a heart beat. over all the quality of their Employees is Low at best which is why they pay them in peanuts. I would stay very very far away from this place. Unless you are someone who likes to lie and cheat and steal!

Pros

They post the policies they violate. Retaliation is fast and efficient. Harassment comes with teamwork. No paperwork = no problems, right? EEO stands for “Eventually Evict Outsiders.”

Cons

Disabled? You're disposable. HR stands for “Harassment Repackaged.” Float staff = Mean Girls with needles. Policies are decorative. File a complaint, win a surprise firing.
