Mapper, may I ask if he gives you his paychecks? Have u ever physically been where he works? Have u ever talked to his boss?
I am getting the feeling he is not even going to work but spending time at the library or a coffee shop and using free WIFI.
I really don't know any kind of an employer that would tolerate his abscences even if they are only paying him when he is there and doesn't care about the rest.
