Pretty soon though, the team started to see issues with the update, up to and including a major LoB system going down. They immediately rolled back the update but found they had a problem- they needed some servers restarted to pick up the update, and the sole person who by union rules could restart the server had left for the day and wasn't picking up the phone.
Now there were people who technically had permissions to restart the server, but they couldn't cross the union rules. They spent over an hour (with the major LoB, business critical system down) trying to get in touch with the people who were allowed to restart the server until they finally convinced the physically datacenter ops people (who were still on duty) go physically unplug and replug the servers in question.
He couldn't disclose the total cost of the outage, but I was lead to believe it was in the millions of dollars.
A functioning owner/management/worker relationship might fight over how the earnings of a company might be split, and even how or what to invest in, but they should all be working to making a company successful as a whole. An adversarial relationship prevents the sort of cooperation and good-faith assumptions that allow the different parties to collaborate and work to everyone's benefit.
That being said, that non-adversarial relationship is a two way street, and ownership+management need to be participating in good-faith as well.
