Cerner is a great place to work. There are a lot of good perks and some managers are very family friendly. The huge drawback in a poor, uncompetitive maternity leave. I don't know that I would recommend Cerner to someone who is thinking of starting, or growing, a family.
At my company there are a lot of women and a lot of women in management and executive roles. However, within my department I would say it is definitely more male dominated. I've consistently seen males promoted more. I also know of a number of males who have been in lower positions as myself, employed in the same roles for the same amount of time as myself, and got paid significantly more.

Things are a lot worse at other companies, I'm sure. This company isn't terrible but it isn't perfect.
