As a supervisor in a Child Care Center, write the solution for the scenario below

Behavioral issues: "I'm worried about Joan. She is usually so boisterous and pleasant, but lately, she has been really quiet and withdrawn. She's not participating in curriculum meetings or sharing her ideas with the team teacher. I get the sense that she doesn't like her job anymore. She's not putting the effort into her work as she used to. I can't tell if something is wrong or if she has just changed her mind and doesn't want to work here anymore."
