On my last job, a new manager called me for a meeting on Friday 4PM. I spent the whole month on an extremely stressful project.

When someone tells you to do something that's both impossible and utterly unreasonable, just stick to telling them it's impossible.

This manager needs to be fired hard, or he's going to bring that company down.
