Someone who uses a job to work on something other than that job. Someone who lies about where they are, claiming they are doing their job. Someone who claims hours on a time card that can't possibly be true.
A: Dan said he worked from home on Saturday for 26 hours!
B: Really? John said he saw him out looking at used cars this weekend.
A: Do you think he is claiming hours and he is not working?
B: Oh he may be busy, but not at the job he was hired to do. I am sure his Doctoral Dissertation will be the best in his graduating class based on the hours he’s claiming.
A: He's a real programmatic prostitute.
