For the life of me I've never understood this complaint.
I never worked long hours at Cisco. I never worked long hours at any job prior to Cisco and I never work long hours at my current job. The reason for this is because I'm not some virtue signaling mark willing to bend over at a moment's notice for a company that will be all too eager to take advantage of me. I draw a line in the sand from day one because I have some self respect and backbone unlike the bootlickers.
What happens if I don't work long hours, will I get fired or something? Who cares. I'll just find another useless job at another toxic company. Those places are a penny a dozen here in the valley.
Enjoy checking your emails and IMs all weekend while I'm relaxing.
