The jabs Erin Parker has heard about her job have stunned her. Oh you pathetic teachers, read the online comments and placards of counterdemonstrators. You are glorified baby sitters who leave work at 3 p.m. You deserve minimum wage.

“You feel punched in the stomach,” said Ms. Parker, a high school science teacher in Madison, Wis., where public employees’ two-week occupation of the State Capitol has stalled but not deterred the governor’s plan to try to strip them of bargaining rights.

Ms. Parker, a second-year teacher making $36,000, fears that under the proposed legislation class sizes would rise and higher contributions to her benefits would knock her out of the middle class.

“I love teaching, but I have $26,000 of student debt,” she said. “I’m 30 years old, and I can’t save up enough for a down payment” for a house. Nor does she own a car. She is making plans to move to Colorado, where she could afford to keep teaching by living with her parents.
