Pros
Initially, the best thing about Mercury was they let our day to day operations remain very similar to how they functioned prior to the acquisition. That's about it.
Cons
They treated everyone like they didn't matter. They lied to our entire company about the changes in the pipeline, they hid information from our management group and worst of all, they lied to our entire company about people being able maintain their positions. They went as far as to lay people off, including myself, in the middle of the week without any warning nor informing our bosses and then asked us not to tell them. Once we were out, we became a zero priority in regards to getting our final pay checks, maintaining communication about the next steps of our new unemployment and informing the company managing my retirement fund that I was no longer there. Their priority isn't their employees, it's their share holders.
