I worked at Cisco from 1999 to the end of 2014. I agree that it was an extremely stressful working environment. I survived numerous restructures and layoffs as a manager.
The impacts of a globalized workforce collaborating and communicating across multiple time zones has pros and cons. I believe it takes a toll on the physical health of many. However, diversity is a wonderful thing as it brings many perspectives and experiences to any given project.
I wanted to keep working for a few more years, but after my team was abolished, I had no more energy left to give. I was grateful to get a package myself at the age of 64.
It's a tough environment at Cisco, but it truly was a great company. I've been away for over a year and not sure I would still say that about the company. I wish everyone the best!
