I don't get helpers very often. But I did pick one up last year.. helper coordinator told me it was her first day out and they wanted to get her some experience. The route I was covering is about 50/50 commercial and resi so I worked on DIAD skills and she caught on quickly. Turned into one of best helpers I have ever had. The regular driver came back to the route next day and the helper worked with him the rest of peak.
She now works on preload and is a utility driver and will be on road this peak.
Oh and we live together now. Never know what a day at UPS will hold in store for you when your a cover driver!
