Posting for traffic. A colleague has threatened to 'get' my DB after work. Absolutely zero provocation. DB is the most harmless person you'd ever meet! This man has made similar threats and horrible comments to other staff as well, some of which has been reported to the managers - but nothing has been done. My DB feels unsafe and stressed working there, but what can be done to get this man out if just reporting it makes no difference? What are the next steps? Would the police even take it seriously as it's just DB's word against this man's? There's no HR department and only the head director left to escalate to. Any advice please?! DB deserves to be able go to work without threats of violence and abuse.
