I run a daycare and have done so for 7 years. I have a great relationship with the kids and parents. However, I have a week off now and as pathetic as it sounds, I am worried the kids will prefer my colleague who is covering me. I worry the parents will as well. Although she doesn't have my experience and qualifications, she is more confident then me. I worry she will undo all my good work and the parents will wish she run it instead of me. Is it possible for this to happen and how do I help manage these emotions and feelings of jealousy?
