Sounds too much like real life - I have two employees out on medical leave (surgery), one resigned to move with her hubby and I can't replace her - - - getting to be pretty challenging. All the while, they've added a new responsibility for me - - to maintain all the company's office supplies - - whew!
You know the saying...'With great power comes great responsibility'.
Glad they recognize how awesome you are!
