I had a former worthless son-in-law who was fired from a very overpriced very underqualified job because he took a sick day and then reported in long conversations on social media that he was kicked back on the couch with a brewskie, a sancwich and a ball game. Even commented on how much better it was than work. A suspicious, had-enough-of-it fellow employee forwarded the link to the owner of the tech startup. Add stupid to the qualities. Sometimes smart people know when to show restraint. I believe the boss likely questioned the rat about why they saw the post.
