I was working as a Major Incident Manager for a very large consulting company working on a huge government project. The management in the consultancy company were generally terrible, on my first day my colleagues took me out for a drink - they pointed out a bunch of people across the room and mentioned that it was the configuration management team who had all just been fired because management weren't happy with the way the process was going...just as my first example.
Another time I had someone from second line support come to my desk and point out that some of the monitoring was showing red, I immediately directed one guy to check from an end-user perspective to see the actual impact for users, another guy to pull the logs, and a third to dig deeper into the monitoring - they all scurried away to start assessing the situation. In the mean-time I leaned over the partition to my boss who was sat next to me, and mentioned the issue - she stuck her head up like a meercat, looked around, and said (quoting word for word), "I can't hear any shouting, I can't see people running around, I can't see people panicing, I don't feel this is being managed properly!". She then asked me if I'd informed her boss yet - I told her we were still evaluating the situation (again, apparently unacceptable), so she immediately snatched up her phone and called him saying the monitoring was red and we were in a crisis. Just as she finished her call the guy from the end-user perspective came back to my desk and reported that the issue was completely transparent to end-users. I passed this news to my boss who threw her hands up and said, "But I've called X! Now it's nothing?!". Yes. Quite.
A third story would be from the time her replacement (she was eventually demoted then fired) pulled me to one side and started screaming and swearing in my face because he didn't feel I was motivating technical staff to fix issues quickly enough because I wasn't in their faces screaming and swearing at them until any issue was fixed (yes - this is exactly what he meant). I'm sure any techies here will be happy to agree that this is not an appropriate motivational technique to get the best from your staff...but there you go.
I could go on - but instead I'll just summarise to mention that in the 12 months I worked there everyone in my team quit or was fired and replaced twice over except for me and one other guy...when my contract finished I wasn't sad to leave.
