Workplace smoking laws apply to any enclosed workplace.
Smoking is prohibited anywhere other than designated smoking areas. Smoking is permitted in designated smoking areas.
In Kansas, smoking areas must have existing barriers and ventilation systems to minimize the toxic effect of smoke in nonsmoking areas.
Kansas doesn’t specifically require employers to provide workplace accommodations for nonsmoker employees.
Kansas employers must have a written policy prohibiting smoking without exception in all areas of employment. The policy shall be communicated to all current employees within one week of its adoption and to all new employees upon hiring. The written policy should be available upon request.
A Kansas employer may not discharge, refuse to hire, or take other adverse action against an employee in retaliation for reporting or attempting to prosecute a violation of the state's smoking laws.
If you want to go right to the source and look up Kansas law on workplace smoking laws -- or if you're writing a letter to your employer or employee and want to cite the applicable law -- the relevant statute(s) can be found at Kan. Stat. Ann. Sections 21-6109 to 21-6116. Workplace smoking information is also available in Nolo's books Your Rights in the Workplace, by Barbara Repa (Nolo) and The Employer's Legal Handbook, by Fred Steingold (Nolo).
