Pros
In general I’ve found working at MKS to be a good thing. The people I work with are excellent. My group leaders and management are good. There has been over the years several excellent managers to work with. Things come and go, and overall I found the culture of MKS to be reasonably supportive and adaptable to employee needs.
Cons
I think the company tends to undervalue its employees. At least those who are not on salary. I am an hourly employee. Although I have consistently been rated as competent or above confident in the performance of my job, I very rarely get anything more than a 2 1/2 to 3% increase in my yearly salary. Essentially, I got enough to cover inflation if it’s a good year. I think MKS would be served by more generously compensating its hourly employees.
