As the title and description explain....
If a Service Level Agreement has not been met, meaning the time has expired and we are now operating in SLA Overtime, it would be beneficial if an assigned/designated supervisor is notified via email.
Additionally, and in the same spirit, it would be beneficial if the supervisor and assigned agent could be notified at a designated time prior to the SLA expiration. This would serve as an alert that failure to meet an SLA is pending. is this case, actions can be taken to realign resources if deemed necessary in order to meet the SLA.
