Office culture varies widely from place to place but these tips apply from the most relaxed start up to a downtown corner office.
Don’t default ‘reply all’. Keep ‘reply all’s’ to a minimum and only when the whole group is interested in your answer. When sending a group email where replies only need to be directed to you, consider BCC. Instead, be a good email-er and preface subject lines with FYI: or Response needed.
Don’t abbreviate words. Your colleagues deserve the same respect as clients. Keep the language in emails and other communication grammatically correct (and brief). This helps prevent confusion and keeps you looking professional. Additionally, turn off the caps lock. Beyond an overly-long acronym, it has no place in the workplace.
Don’t forget that sound- and smells- travel. In an open office, chomping and chewing or reheated lunches can easily grate coworkers’ nerves. While that leftover garlic pasta is delicious, it’s best to not use the communal microwave to heat it up.
