Low pay/undestaffing

Pros

- some in-office-phlebotomist (IOP) positions are very slow which grants you time to respond to emails, study, or manage other sedentary tasks

Cons

- low pay and did not budge at all when I requested higher pay to reflect my previous work experience/previous pay - very poor communication between management and IOPs. I feel like I'm an employee of the clinic where I work (which is great! the clinic staff are amazing), but I do not feel like I'm an employee of Quest Diagnostics, nor do I particularly care about the company - working for a company that hires so many phlebs will make it easier to find work, but it almost certainly pays less and is a less cohesive environment than direct employment by the clinic or hospital itself.

Pros

Steady, job insurance, decent benefits.

Cons

No room for growth, leadership lack skills and decency, no support. Leadership would rather harass employees while on LOA, speaks condescendingly and overall rude.
