Pros

Opportunity for growth, many positions in different regions if that is an option ine wants to explore, competitive wages, many perks.

Cons

Favoritism amongst management, individuals are not getting positions based on merit , experience and knowledge, but who they know and are friends with, people getting undeserved positions created for them after not performing well in their position, unqualified people (kids of friends of management) getting made up positions as a favor.....

You're gonna work holidays

Pros

They leave you alone to do your job. You start with 3 weeks off per year (that you accrue weekly). After one year that goes up to 4 weeks accrual per year.

Cons

They make you work holidays and you don't get time and a half for working on a holiday as you may expect. Management shows favoritism towards selected individuals and they make it VERY obvious. The yearly salary raise is ridiculous. They have the nerve to give hourly employees less than $1/hr raise in a year which is outrageous considering current inflation rates. You're gonna be working with old pipettes and half broken equipment. Management makes no effort to replace day to day items that are essential to your job. You dont get paid maternity leave. You get 2 months off and if you want to get paid you have to use PTO and/or short term disability which is 60% of your pay(SUCH A JOKE). Management is against employees moving from department to department.

Pros

I met some really awesome people who I loved working with and the pay isn't too bad.

Cons

Upper management is atrocious. A lot of favoritism. The harder you work the more you get crapped on. God forbid you have any grievances, if you complain, you're the bad guy. Problems are never addressed. I can go on.
