There shouldn't be any chat at all. This crap just creates unnecessary opportunities for liability. The only purpose for these chat services is to create attack surfaces for plaintiff lawyers. In banking the government saddles the banks with logged chats and recorded phone lines that get forwarded to regulators. Yet now in tech the industry has saddled itself with risk without even being forced to, bombarding employees with pointless notifications to boot through these insipid, time-wasting chat services. It is very bad for employees because employees are the sacrificial goats for shareholders. The catch all escape for liability is 'an employee did it' followed by 'a manager did it' followed by 'an executive did it.' These chats to some extent make it easier to sacrifice peons to the government and/or civil plaintiffs but it also makes it harder to fend off such conflicts in the first place by just making it harder for the other side to find any dirt.
