Sometimes, a simple reassurance or explanation suffices to close-out a grievance. This typically happens with grievances expressed verbally in the context of a meeting. Such grievances should still be logged, categorised, rated, and closed-out, but they don’t need to be responded to or investigated.
Note that if there seems to be a recurring pattern in the type of grievances resolved on the spot, it could be an indication that the site needs to improve its engagement and communication on the topic in question.
