Are there some days at your job when just don't feel like doing any work at all?

Have you ever gone to work and felt like or planned on actually doing no work at all?

Why did you feel this way? Did you actually do nothing? Was it because you were lazy, too tired to work, or some other reason? Was it a day when you needed a mental or physical break? Does your job prevent you from being able to do minimal work for a day? If not, how did you get away with it? What did you do instead of working?

How many days a year do you feel like this and how many days have you actually done nothing?

Should there be a national Go To Work, But Do Nothing Day?
