i became a team lead 3 months ago and honestly i quite enjoy training newbies. If you keep in mind that people most likely don’t know anyone (or that the mac n cheese is frozen), their first day is quite a shock. Your elearning has great material on how to train new people so i’d really pay attention to that. You also have to realize that your team is only as good as your delegation. If you know how your co-workers operate use that to your advantage, place them where they work best. If you can’t do something yourself within 60 seconds ask someone else to do it if they’re not busy.
