MO SB510

Redefines "misconduct" to include conduct or failure to act connected with work that demonstrates knowing disregard of employer's interest, carelessness or negligence manifesting culpability, violations of no-call/no-show policies, chronic absenteeism or tardiness, or violations of employer rules that employee knew or should have known about.

Adds specific misconduct categories including knowing violations of state standards by licensed/certified employers and two or more unapproved absences following written reprimand for absence unless protected by law.

Narrows "good cause" for voluntary quit to only causes that would compel a reasonable employee to cease working or require separation due to illness or disability, removing broader previous language.

Eliminates previous provision that absenteeism or tardiness could constitute rebuttable presumption of misconduct regardless of whether last incident alone constituted misconduct.

Maintains exceptions to disqualification for voluntary quit including acceptance of more remunerative job, return to regular employer, pregnancy-related separation with medical proof, and military spouse relocation.
