Hey Amy, are you using a Call Queue right now? One thing you could take advantage of would be the Rotating or Sequential setting so that you can have more control over how often the new hire receives a call
We have 4 call queues. Some agents are in multiple queues. We are using Rotating setting but that doesn't help. Sequential may assist a little but not enough for a newbie who needs more breathing time.
Would creating an overflow queue for your newbies work? Put all of your experienced Agents in one queue and all the newbie Agents in the overflow queue. They will only get calls when the experienced Agents are busy. As they get more experienced you could add them the the experienced queue
