Back when I used to lead the engineering group for a company I was asked to also lead the IT and Ops teams. I was amazed at how many of the sys admins lived in fear that anything going wrong or taking a risk on something new and it not working as expected would get them fired. Virtually no one wanted to take any risks because of this fear. It took a long time of working with the team and demonstrating that people did not get fired when things went wrong. It was a real eye opener for me.
