On your team settings panel, you will have the option to remove any member from your organization. Removing them would affect the escalation policies they are part of. Our dashboard will show you the number of escalations that could get affected along with the open incidents that the member is assigned to right now. Once removed, no alerts will be sent to this member.
The user gets automatically removed from all escalations policies they are part of. So, if a escalation has two users A and B wherein the first alert goes to A and 20 minutes later the second alert goes to B; if you choose to remove A then the escalation policy will always send only one alert immediately to B.
Incidents which are not resolved are open incidents. If there are any open incidents assigned then we recommend you assign them to someone else from your team. Alerts about only these incidents are sent to the user after they are removed too. So, we suggest you reassign them soon as this member is removed.
Yes, we give you the option to add this same member back again. However, you will have to add them again to escalation policies and re-assign them incidents.
Remember that this is not the same as undo-ing the removal of a member
