I think Cisco has lost the plot. In the past 6 months I know 7 or 8 people (myself included) who have resigned - some of whom had been there over 18 years.
Not one of them received an exit interview, phone call from HR or anything. No attempt at all to understand WHY people are leaving.
I find it very surprising that there's no desire to find out why high performers are leaving the company... Probably very related as to why it's in such a mess!
