“As one human resources professional said to me, ‘I wish someone would tell twenty somethings that the office has a completely different culture than what they are used to. You can’t start an e-mail with ‘Hey!’ You’re probably going to have to work at one thing for quite a while before being promoted—or even complimented. People are going to tell you not to tweet about work or put stupid posts on your G-chat status. Not to wear certain clothes. You have to think about how you speak and write. How you act. Twenty somethings who’ve never had jobs don’t know this. Neither do the scanners and baristas who’ve been hanging out at work chatting with their friends.”
