The district suggested they begin raising the wage in 2020, but the union wants it to start next year.

The Saint Paul Public School District believes if they raise the wage next year, they wouldn’t be able to manage the district’s expenses and classroom resources.

Cafeteria workers point out that earlier this year, the district agreed to a contract with teaching assistants that will raise their base pay to at least $15 an hour by next school year.
