Pros

Clean, fun place to work

Cons

Overworked with the amount of people coming in. Management lies to you constantly to keep you coming, will not advance you but give you the work of a supervisor

Pros

They'll train you in the lab in any area you're interested in.

Cons

As a lab assistant, they do not care about you or making your job harder if it makes the life for the techs a lot easier. People will report you for any little thing you do. You can breathe too loud and someone will report you.Pay is not at market rate.
