Shoutouts are a non-monetary way to recognize your peers! Think of it as the digital version of a physical box in the middle of your workplace where you can quickly recognize your fellow team members for great work.
Your Team Admin (or Managers with budgets) may send Guusto gifts as they see fit based on the shoutouts, or perhaps enter members into a draw for every shoutout they receive to potentially win a larger prize, like a vacation. Reach out internally for more details about when and why to shoutout a peer! :D
