While attitudes towards marijuana have generally softened, coming to work stoned can be grounds for termination since Illinois employers may prohibit illegal drug and alcohol use by employees at the workplace. Employers often codify these prohibitions with a drug-free workplace policy. They commonly include these types of provisions:

  • marijuana, marijuana abuse, marijuana use at workThe manufacture, distribution, dispensation, sale, possession or use of alcohol, illegal drugs or controlled substances while on duty or on employer property is prohibited and will subject employees to immediate discharge.
  • Employees who are impaired by or under the influence of alcohol, illegal drugs or controlled substances, or who have any of the same present in their bodily systems while on duty or on employer property, will be subject to discharge.
  • Each employee must notify the employer of any conviction under a criminal drug statute that the employee receives for a violation occurring while on duty or on employer property within five days of such conviction.
  • Employees may be required to submit to a drug and/or alcohol test as a condition of continued employment. Employees who fail to submit to the required tests and/or test positive for alcohol, illegal drugs or controlled substances will be subject to immediate discharge.
