Business Outlook

Pros

Good benefits and they pay fairly well no matter what position. Company is doing well overall with no danger of layoffs.

Cons

obscene amount of micro management. Department managers are insane with monitoring every little thing an employee does. Control freaks.

Over worked and underpaid

Business Outlook

Pros

Time off is average at best.

Cons

Inconsistent polices that apply to some people and not others. Management expects above and beyond without recognition, or even a thank you, nevermind pay that is appropriate for the amount of work. Constantly understaffed.

Great Benefits, hard company to work for

Genetics counselor

Recommend

CEO approval

Business Outlook

Pros

The benefits are really good, which makes this a very hard company to leave. My management is understanding and generally good people. Work life balance is good because they don't expect you to work more than your 40 hours. There are always opportunities to grow.

Cons

The company makes it hard to do your job, so many hurdles and steps to do something easy. The health insurance costs keep going up and the amount you owe does too, which is disappointing in such a large company. Genetic counselors are not well respected as medical professionals, value MDs more. Feels very male dominant heavy at times. They assign you more work than you can do and expect you to do everything because no one is invested to help or improve things. You get beat down by the systems.
