I agree with your assessment of ADP executive management. It has not been a secret that moving up in ADP is about who you know rather than what you know. Many upper level executives have no clue that the company is run by the individuals who are trying desperately to give clients the best possible service with broken products and ineffectual tools. In essence, they can't see the mass exodus of clients who don't want 65 year old tools and the BS excuses given to them for the lack of experience in the new hires (which is not their fault, by the way).
The mass walkout occurred when 6% of the total employee population was offered a voluntary retirement package that only 30-35% were expected to accept. Instead, more than 70% accepted the terms and left the company and taking great knowledge with them. Since then, employees have been pushed out via layoffs, RIFs or firings almost every single month.
ADP will not collapse but they will never gain back the industry respect they once had as long as Carlos is running the show.
