The sitter we hired through Sittercity had a driving record (we had a private background check run as they did not require it) She had evictions.
She left our infant unattended and tried to steal furniture. She tried to coerce us to follow her outside so she could claim we were assaulting her. Our neighbors were witnesses to this madness! Sittercity still has her on their site as of today.
They were sent evidence including voicemail of the sitter admitting she was guilty of the above. Sittercity is in possession of the admission from the sitter via voicemail of leaving an infant alone in a house in a high chair unattended, stealing furniture and stealing keys to the house. They have chosen to leave this baby sitter on their website for other families to hire, knowing that she has admitted to these atrocities.
