The confrontation came on the heels of relatively good news: Discussion between board and union representatives appeared to take a positive turn. That was the word from both sides.

Nicholas Alajakis, the spokesman for the Waukegan Public Schools, did not dispute that.

“The sides today did have some positive talks,” he said.

Both sides were expected to resume negotiations Wednesday morning.
