No, time spent in Focus doesn’t appear in any reports. Agents who may be spending too much time in Focus or using it outside of its primary use case would see their occupancy numbers decrease as they’d be handling fewer Contacts and helping fewer Customers. Agents spending too much time on Focus may display higher handle times and after Contact time.
Staying in Focus mode for an extended time after a Contact ends (e.g., after a phone call) would increase their After Contact Work Time number. If an Agent put themselves into Focus while not handling a Contact, that will impact their occupancy numbers (important if you measure occupancy), as no additional work will be routed to them while they are in Focus mode.
