I often times clock in at work then immediately go take a nap. Do you think that's a problem?
You're that tired when you get to work?
No, I just feel like I shouldn't have to work.
It sounds like you may not like your job. It's expected that when you take a job you'll fulfill your obligations to your employer. If you get caught, you may get fired.
Ok, I admit defeat. I dont like my job.
Change occupations, man. Life is too short to work a job you dislike.
