Drug and Alcohol-Free Workplace

CST  expressly prohibits the following activities at any time that employees are either on duty or conducting CST business either on or away from CST’s premises:

  • The use, abuse, or being under the influence of alcohol, illegal drugs, cannabis or other impairing substances.

  • The possession, sale, purchase, transfer, or transit of any illegal or unauthorized drug, including prescription medication that is not prescribed to the employee or drug-related paraphernalia.

  • The illegal use or abuse of prescription drugs.

Nothing in this policy is meant to prohibit the appropriate use of over-the-counter medication or other medication that can legally be prescribed under both federal and state law, to the extent that it does not impair an employee’s job performance or safety or the safety of others. Employees who take over-the-counter medication or other medication that can legally be prescribed under both federal and state law should inform their direct supervisor or HR before reporting to work while under the influence of that medication, if the medication may impair their job performance, safety or the safety of others or if they believe they need a reasonable accommodation.

A violation of any of the above will result in discipline up to and including unpaid suspension and/or immediate termination of employment.

Employer-Sponsored Events

From time to time, CESO may sponsor social or business-related events at which alcohol is served. This policy does not prohibit the lawful use or consumption of alcohol at such events. However, if employees choose to consume alcohol at such events, they must do so responsibly, in moderation, and maintain their obligation to conduct themselves professionally at all times with colleagues and/or current or prospective clients.


Although Minnesota law may provide some form of protection for use of cannabis, a job applicant or employee may not use, possess, or be impaired by cannabis on CST premises or while working anywhere on behalf of CST. The use, possession, distribution, or being under the influence of cannabis is strictly prohibited on company premises, during work hours, or while operating company vehicles or equipment. Employees are prohibited from reporting to work under the influence of cannabis or any substance that impairs their ability to perform job duties safely and effectively. Failure to adhere to this policy may result in disciplinary action, up to and including termination of employment, particularly if an employee's actions violate state laws, compromise safety, or impair job performance. CST does not discriminate against job applicants or employees enrolled in the registry program established under Minnesota Stat. 152.22-152.37.
