1. "Employed" people who have jobs and go to their jobs. These people vote.
2. "Underemployed" people who have jobs that are beneath them but they go to them anyway because they have to. Also voters.
3. "Unemployed" people who who want to go to a job but cannot find one. A lot of these people vote, too.
These are the people who are watching public employees not working during the workday.
Good luck with that.
