Where do I get assistance for someone to come help my Mother while I am at work?

Half my family feels my 87 yr old mother should not be left alone while I am at work for more than a hour at a time. she is able to dress and feed herself, keeps herself clean. not sure where to turn to or who to ask about getting a assesment on her to satisfy my family that she is fine without having someone with her 20 hours out of the day
