Voice, Mailing your

A polite librarian should help library colleagues keep their overburdened inboxes clean by opting for long, rambling, hyper-detailed voice mail messages in lieu of email.

Blame, Generalizing

The best way to correct a fellow coworker's breach of library protocol is to send an email to everyone at your workplace reminding them of the policy that one person violated.  Humiliation is best served passive aggressively. And via mass email.

Battles, Email

If you are going to subject your library coworkers to a fiery toned public email battle with another colleague, at least try to make it interesting. Nobody wants to read fifty back-and-forth argumentative emails about your use of the MARC record's 856 field. Consider your audience... use more expletives, insult the other person's cats, and ramp up the obvious sexual tension. Your readers deserve better.
