Emojis in the office: have they made your emails not suitable for work?

Name: Workplace emojis.

Age: 25. The first set of emojis hit Japanese phones in 1997.

OK, but why did you just email me a yellow waving hand? Just being friendly with a colleague.

Never. Well, I have very occasionally succumbed to the skull. And what do you use it for?

If pressed, I would use it to inform people that my legendary baba ganoush is available in the third-floor kitchen. This is where some of the worst problems arise: older workers sending colleagues emojis that are distinctly not safe for work. A winky face is considered not just jokey but flirtatious by younger people, and anything with a tongue, peach, taco or aubergine is strongly discouraged.
