That's rough! My suggestion is to go to your boss and see if you can delegate your duties to others. Or, delegate some of your duties to the newbies. When I've had to train a new employee or two, I've found delegating tasks to them made my job easier, allowed me to focus on their training, and gave them skills they needed. But if that's not possible, you need to plan out how you want to train them and still manage your duties. If you can give them a task and let them run on their own, then check their work afterward, that can be another solution.
