According to a report in the News-Leader, one worker got a 30-day suspension and a demotion. The other can't be promoted for a year.
From the story:
Last Tuesday, CU launched an inquiry into allegations that its employees had stoned a cat to death. ...
International Brotherhood of Electrical Workers Local 753, the union that represents the two employees, conducted its own investigation last week and "two members stepped forward (to note) that they probably did something that was inappropriate," said Brad Stokes, IBEW Local 753's business manager.
"(The local union) has a code of excellence and we expect members to (live up to it)," Stokes said. "They have stepped up and apologized for that. They'll suffer the consequences as a result of that."
