There is a slight difference. Slack is used by workers for personal social interactions as well. For many workers Slack is as much a social media tool as it is a work tool. Many workers actually prefer to have slack open during off work hours to share memes with their work buddies. Even for workers that don’t engage in social activities over slack normally might install it to their personal devices during a conference because that is where their colleagues are conversing, and then simply forget to uninstall it after the conference is done. A workplace has to be aware that this is how normal people use this tool, and needs to make sure that no one misuses this access to workers during off hours.
