Is unemployment understated?

Mort Zuckerman in The Wall Street Journal says, "Yes," and gives ten reasons. Among them:

- More companies are asking employees to take unpaid leave. These people don't count on the unemployment roll.

- No fewer than 1.4 million people wanted or were available for work in the last 12 months but were not counted. Why? Because they hadn't searched for work in the four weeks preceding the survey.

....
- The average work week for rank-and-file employees in the private sector, roughly 80% of the work force, slipped to 33 hours. That's 48 minutes a week less than before the recession began, the lowest level since the government began tracking such data 45 years ago.
....
- The average length of official unemployment increased to 24.5 weeks, the longest since government began tracking this data in 1948. The number of long-term unemployed (i.e., for 27 weeks or more) has now jumped to 4.4 million, an all-time high.
