This did not happen to me, but someone close to me.
Someone that works for a very large west coast Electric and Gas company threatened to come back to work and shoot up the place. All the managers and supervisors know about the incident along with the HR dept. They initially scheduled some “Active Shooter Response” classes but have so far rescheduled three times with no actual date on the calendar. As of yesterday, 20 September 2023, no one within the company or the union have contacted the police nor have they made any additional security measures. A lot of employees are worried about what might happen next. Supposedly, the union reps and HR “took care of the matter and that this is a safe working environment.”
