A BLS news release said the number of union workers went up by 428,000 to 16.1 million. The union membership data was collected as part of the Current Population Survey (CPS).
According to the BLS, other 2008 data highlights included that:
- Government workers were nearly five times more likely to belong to a union than were private sector employees.
