Warren, Michigan (WXYZ) - The Warren Consolidated School District sent out a letter to parents on Tuesday, explaining in detail why they had to cancel classes.
"By 8:00 a.m today we had a total of over 750 staff call in absent, making our decision to close school a very smart and prudent one for the sake of our students," read the letter from Superintendent Robert Livernois, PhD.
He explained that the district simply could not replace enough staff members to operate.
The staff members called in sick because they wanted to protest Right To Work legislation in Lansing.
"It was a little frustrating and stressful, because it was sudden," said Leah Benard, a mother to 2 Warren students "We didn't know what was going on, and if them even being up there is going to do any good."
She had to take her children to work with her, until fellow Warren parent Jaime Mortimer relieved her.
Mortimer says she has heard the complaints from other parents, that the teachers should not have called in, because kids need their education.
"I am making this into a lesson," said Mortimer. "They are learning quite a bit more than they would in a single day of school. They are learning about politics."
She says after telling the kids about what was happening, the kids actually wanted to make signs for their teachers.
The Warren Consolidated School District is not the only district that had to close due to the number of staff members who called in. The Taylor School District and Fitzgerald Public Schools also canceled classes.
