The South Butler School District is canceling classes beginning Thursday.
The district sent parents a letter Friday saying classes except those at the Butler County Area Vocational-Technical School will be canceled beginning Thursday.
The teachers, represented by the South Butler County Education Association, have been working under terms of their last contract, which expired in 2014. The union issued a strike notice last week saying they would strike if a new contract isn’t settled by Thursday.
Negotiating sessions were held this week and more are scheduled for next week.
