Congrats
From LinkedIn’s automated suggestions: “Congratulate so-and-so for starting a new position as x at y.”
I like the idea of acknowledging friends, colleagues, and connections for landing new jobs.
But I think it would be just as reasonable to have a prompt to congratulate people for leaving positions. To congratulate them for walking away at the right time. To congratulate them for taking a leap out rather than a leap in.
Because walking away can be just as brave and praiseworthy as landing a new position.
