sherk /'sherk'/ (noun) someone who both shirks
responsibility to do their own work and steals credit for another person's work, especially to advance themselves at the other's expense.
Etymology: triple
portmanteau of "shark" (in the sense of a predator of other's efforts), "shirk" (to avoid work), and "jerk" (a contemptible person).
"Katharine Parker's character in the 1988 film 'Working Girl' is a
canonical example of a sherk, an unscrupulous boss who steals her employees' ideas and claims credit for their work, while contributing nothing of value herself."
"
Republican Senator Roger Wicker of
Mississippi, who voted 'no' on the $1.9 trillion American Rescue Plan, later tweeted that he deserved credit for passing the widely popular bill, confirming once again that he is an 'odious sherk' as his critics have charged."
