Pros

There are no pros to working here

Cons

Terrible management, claims work life balance but be prepared for 2 hours of OT every single day, too many call ins, environment is toxic, not allowed to talk to other employees, pay is horrible, machines constantly breaking down because the company won't spend money, the lab is constantly too hot to work in, and the only time things get done right is when the manager is in the lab and the supervisors actually work/help. Probably the worst job I've ever had.

Pros

I enjoy how independent the job is. Most days are the same and there’s rarely unexpected things that happen.

Cons

Long tenured employees have contributed to a negative morale. Department to department communication is especially poor. No routes are exactly alike, thus the pay structure doesn’t reward you for driving in higher crime areas, longer routes, more stops, more specimens collected, etc.

Pros

The training was good and team lead care about her employees.

Cons

Round the clock work, with very little time for breaks. Mundane, monotonous work that can drive you insane if you let it.
