Estimated Completion Date

What is your definition of estimated completed date? Do you think January 2008 is a good estimated completion date? Apparently it's not. The jackass coworker gave me a lecture in front of everyone with his high almighty voice that it's too open ended. But that's what estimated completed date is. It's suppose to be open ended to allow flexibility. Whatever. Someone has a stick up their ass. I'm pretty much ready to just throw in the towel and call it a good run. On my way home last night, I was preparing a 2 weeks notice speech for my boss. I'm tired of him. I've put up with his crap for a year and a half now and I'm not getting paid enough to deal with his attitude. I've tried to stay out of his way. Tried being nice. But after his little fit today, I was ready to go off at him. He has more mood swings then a girl on pms. I need to update my resume asap.
