 But the New York Post continues, on Reddit, some were less offended by the thumbs up emoji, but felt the heart symbol was actually the most inappropriate. Quote, to me, the heart is reserved for family and friends and has a more intimate meaning of love, while thumbs up is just simple agreeing, commented one person. I actually find a heart emoji weird for work messages. I use heart emojis for things like when someone says, I got a new kitten, or Susie did a really great job, added another.
