CHICAGO — A state board will decide whether a threatened walkout by the Chicago Teacher’s Union is legal.

CTU is planning the walkout for one-day on April 1 because of a contract dispute.

The union’s House of Delegates must approve it first this week.

CPS says the walkout would be illegal and says any teacher who calls off without a doctor’s note will not be paid that day.

However, the Illinois Educational Labor Relations Board must decide whether a strike is legal and what, if any consequences cps can impose on staff.
