Keep in mind, the drivers for these apps often take these jobs because they can't hold down a normal job. Either due to disability, mental health, or just plain unemployable personality traits keep them from maintaining a normal 9-5. Many of these people can't find other work. They sign up for these apps because they don't have any boss to answer to, they don't have a schedule to follow, and they don't have any real rules that they need to adhere to.
