Gov. Jay Nixon's veto has been sustained over legislation that would have made it harder for workers to receive jobless benefits by expanding what counts as misconduct.
Jobless benefits can be denied to a worker who loses a position because of misbehavior. The unemployment legislation seeks to broaden it to include things like unapproved absences or the violation of a company rule.
The Senate voted 24-10 on Wednesday to override Nixon's veto. The House did not vote on the bill after an earlier vote on similar legislation fell shy of the needed two-thirds majority.
Nixon had said the legislation would broaden the definition of misconduct to cover activities occurring outside the workplace and work hours.
