Why do people do this? Every (functional) place I've worked tacitly acknowledged that Friday afternoon was essentially for low priority tasks; most employees are starting to mentally check out after lunch. Who enjoys meetings enough to want to call one @ 7pm on a Friday? That single event would be enough for me to be starting to email recruiters, it shows that the manager not only has no respect for their employees but is clueless; since it's fairly unrealistic to expect that meeting to be productive. Unless it's a political move to try to force through some unpopular change in a meeting that nobody is paying attention to, which is another deeper level of red flag.
