Our Nanny has worked for us on a 'shared' basis, 2 days a week for the past 2 1/4 years. She is now leaving us to go work for the other family full time as they are expecting their 4th child and have made her an offer she can't refuse. My question is, should we give her a bonus when she leaves? Family and friends say no, but am just not sure - can anyone advise?
