这一段话怎么理解翻译

You are asked to see a 46-year-old man with mild to moderate learning disability and Down syndrome. He lived with his elderly mother until he moved into supported accommodation approximately 2 years ago. He shares his accommodation with another person who has a mild learning disability. They both attend supported work placements 5 days per week and have support workers who sleep over at the house each evening and support them at weekends.The support workers are employed by Mencap.

其中红字这一句话，不好理解。have support workers who sleep over at the house each evening and support them at weekends，have这个词在这里的意思是什么，也没有把握。

请各位多多帮助
