They are and have been negative even before this sh-t. Don't feed the bottom feeders. Let them go through their own truth. Don't let them bring you down into a more negative state.
Narcissism: selfishness, involving a sense of entitlement, a lack of empathy, and a need for admiration, as characterizing a personality type.
They know it all and act like they have knowledge about your position and or status. They don't. These are the ones that make you second guess your thoughts, current status or last status and engage in bashing. If you've been impacted? Seek therapy and not a current angry employee. Not impacted? Seek therapy and not a current angry employee. Feeding the hate, angst or frustration solves nothing. I am not HR. I've already been impacted and vented my sh-t to someone that only made it worse for me. Then I realized the power shift, or manipulation that made it worse. People are fu---d up.
"I know more than you know" right now.
Some employees are just permanently angry and are convinced they are smarter and more talented than anyone else.
Sometimes all we need is TLC.
Wishing everyone the best! Good Luck!
