The benefits of working with people who have different backgrounds are many, especially when you need help solving complex issues or questions about how things work within your organization! Some days I feel like we could spend more time learning from each other rather than just teaching them what they already know (we're all experts).
It's also great having someone else take over some tasks so my workload goes down as well. Having an employee come into support roles can sometimes make it hard for new hires because the team has been together since day one - but this isn't always ideal either. We've had several employees join during their transition period which was beneficial overall though there were times where being able to pick up skills quickly would prove useful if needed right away instead of waiting until after training/orientation week begins.
