Very Poor management

Certified phlebotomist

Recommend

CEO approval

Business Outlook

Pros

Its work . They hire new phlebs cheap so you can get skills there

Cons

Low pay, management is very poor, only "Friends" of the supervisor get ahead. A lot of pushing employees to work harder, work faster, meet unobtainable goals. Very unprofessional leads who are untouchable due to their buddying up with supervisor. If you complain they will punish you or you will lose your job,

Business Outlook

Pros

I gave it two stars because two people in the management were reasonable and HR helped me when I need it—good benefits like the blueprint for wellness, healthy quest, and other programs to support mental health.

Cons

Overview: They will make your life miserable if they don't like you or if you're not a man or a Filipino. Seniors will take advantage of you and treat you poorly. About Managers: favoritism, racism, underappreciated, they will tear you apart and threaten you anytime you want to address toxic culture. Coworkers: a lot of backstabbing, the bad ones are the good ones in the eyes of the managers and vice-versa. Company: They force you and try to brainwash you to be happy with the leftovers they threw at their employees. Underpaid, overworked, and salary increases by 1% every year...are you kidding me? Everything is just backward over there!

It killed my dream

Phlebotomist

Pros

I got nothing good to say about this dump

Cons

Underpaid. Management is not there and sucks. Environment is constantly changing without warning. I was amazing at this job. Consistently good reviews from patients and my PSC is hands down the best in my territory (the reviews say it all) In one year I went from making 15 an hour as a float to 13.82 at a permanent location... and then for al of my hard work I got a lousy 20 cent raise. The amount of work you do and the health risks you take this job should be lying an easy 20 an hour... you can earn more at McDonald’s!!!
