The common gripes were revealed online by office workers fed up with unprofessional emails hitting their inboxes. In a thread the workers agreed 'hey lady', 'hey sweetie' and 'happy hump day' were the most infuriating greetings. 'Any email that starts with 'Hello Dear' – makes me want to punch the computer in the nads,' one woman said. Ensure the sign-off is brief''Sorry to be annoying, but,' and 'Just checking if there's anything you need from me? Finishing off an email with familiar greetings like 'thanks mate', using xs and emojis were also on the workers' most hated lists.
