Various Work-Related Sickness

I had another absence. While I was at home thinking about the absence I made, I came upon this "theory". People used this in their everyday lives, and some may not know about this. Well, I prefer giving it a name.

I have this sickness that I got from my physics professor back in college. But it's slightly different since mine happens every monday. And thinking about it, I came up with a theory:

Monday Sickness

--> One loves the job, but hates the environment/place.

Friday Sickness

--> One loves the environment/place, but hates the job.

Absenticism

--> One hates both the job and the environment/place.

Thinking about it (again), I should have absenticism back in college. There were times that I don't like both the environment and the things I'm doing. But then agan, I didn't have the valid reason to get this sickness. Now, I have all the reason to have Monday Sickness. Try to guess.
