Dozens of Minnesota teachers and teacher union officials will ride buses to Madison Saturday to take part in a union rally against the Wisconsin Legislature’s action this week to strip collective bargaining rights from public workers’ unions.

Three motor coaches will leave at 8 a.m. from the Education Minnesota office in St. Paul; all the buses are full, but there is a waiting list.

The 3 p.m. rally at the state Capitol in Madison is expected to attract thousands.

After the rally, the buses will return to St. Paul, arriving about 10 p.m.
