Pros

It's better than no job I suppose. If you have a good manager, then their unlimited PTO policy truly means unlimited. Depending on the people you work with, you may actually get someone good to work with and managers who care about your growth.

Cons

Low pay compared to average market value. Outdated technology stack with "promises" and "initiatives" to upgrade, but no leadership support to make headway on any of those supposed changes. Not much in the way of growing and/or training opportunities. Their online training portal is lackluster to say the least. The c-suite executive leadership is out of touch on what could actually bring value to the company. Constant layoffs because you incorrectly assumed covid-growth was sustainable? Bad business. As long as shareholders are happy, right? Biggest one of all? THEY WILL NOT HONOR EXISTING BENEFITS IF YOU ARE CONVENIENTLY LAID OFF. Tuition reimbursement, for example? Forget it. Even if you were finished and submitted all paperwork/documentation, too bad so sad. Lawyer told me I have no legal standing to claim that benefit either. You have a HSA or FSA? You can forget that too. If it's funded by the company, that I can understand, but removing all funds even if it's your own contribution? Scummy...

Pros

- PTO - Flexible within some departments

Cons

- The minute I submitted disability accommodations they denied them. - I got in trouble for going out of the lab for water breaks. - You’d get in trouble for chatting with a coworker even if you were still working. - Always increasing specimens accepted to the lab so workers experience an overload. Company is definitely quantity over quality. = stressful workday. - They never listen to employees on how the environment can improve. - Also dangerous location. Car break ins, and auto-theft all day. - Rotating weekends, and holiday hours. - Bad holiday and OT pay rate. (Its time and a half while other company’s are double or even triple time)

Pros

“My Time” policy basically equaled unlimited time off. If you were lucky enough to have a manager that would approve your PTO requests you could take plenty of vacation time.

Cons

No loyalty - employees with good reviews and long careers laid off without cause Poor management - managers all reach a point where their job becomes pleasuring their directors and above. Nothing else is taken into account after that.
