When a family posts a job, it's up to the family to manage that job posting and applicants. Once they find someone, they can either close their job posting so it's no longer visible on the site, or they can let the job posting expire on its own.
Please note that Sittercity is simply an online meeting platform where families can post a job and sitters can apply for that job. We don't know the families on the site or get directly involved in their hiring practice, so we have no way of knowing whether or not they have filled a particular position. We understand this can be frustrating at times, and we’re working on ways to create a better job search in the future!
