I really dislike the "I'm so busy" mentality. Well, I hope for your sake you're busy because otherwise your job shouldn't exist in the first place.
"Busy" has become a trendy word. If you're so busy, how come every time I need to talk to you, you're "away" for one hour at a time & you still manage to log off on time. Please.
Another annoying thing that happened to me today. Some senior guy asked for a copy of an email that my team was cc'ed in. Given the group mailbox was cc'ed, everyone in the team received the email. Yet, someone from my team had the great idea of forwarding the request telling this senior person I can assist with providing the email. Why? You were in cc' too buddy, just look through your emails.
What a team. I'm more and more impressed every day. To say we work for an investment bank - I wonder where they found these people. Definitely not the glamourous image people think of when you mention the industry.
