I worked at Dionex (More than a year)
Dionex took care of it's valued employees and provided room for growth for the people searching it out. A very open door policy company with effective communication.
Somewhat dull work environment and fairly stingy on coffee, carpets, etc. Could be somewhat political at times but you were able to stay away from it if needed.
Advice to Management
At this point there is no advice since the company sold to Thermo Fisher and more or less dismantled the effective teams and folded it into the black box Thermo.
