Yes! Even if you're employed full-time, you can always pick up relief shifts to earn extra money. Relief work is also a great way to try out other hospitals to see if they're a better fit and learn from other doctors. Or, you could become a travel vet, practicing on the road anywhere you're licensed by picking up relief shifts wherever Roo is available.
You never know what you'll find, and Roo is free to join with no membership fees and no penalties for inactivity so you have nothing to lose!
