Oh, undermining your coworkers with grace and ensuring they can't tell? Piece of cake!

First, perfect the art of backhanded compliments. Compliment their work while subtly suggesting they could do even better (wink).

Next, become a master of stealing credit. Nonchalantly swoop in and claim their achievements as your own, leaving them wondering if they even existed.

Lastly, sprinkle your conversations with well-placed sarcasm and passive-aggressive remarks, so they're left questioning whether you're being helpful or just plain annoying.

Remember, subtlety is key!
