Drug and Alcohol Policies on Farms

Farm work involves machinery, animals and driving. A clear policy on drugs and alcohol protects everyone and gives people a path to ask for help.

Why does a farm need a drug and alcohol policy?

Impairment slows reaction time, clouds judgment and affects balance. On a farm that can mean tractors, power tools, livestock and vehicles all in the same day.

A policy tells workers what is expected before a problem happens. It also protects owners and families who often work and live side by side.

A policy is also a statement of care. When workers know that the farm will handle problems fairly and quietly, they are more likely to raise a concern early, which can prevent an injury or a crash down the road.

What should the policy cover?

Describe when and where the policy applies: on the job, in farm vehicles, in housing you provide and during work travel. Explain what counts as impairment, including some legal and prescription medicines that cause drowsiness.

Keep language plain and specific. Vague wording leads to unfair or uneven enforcement.

• Alcohol and illegal drugs
• Prescription and over-the-counter medicines that affect alertness
• Cannabis, which is treated differently from state to state
• Housing and shared vehicles

What are the legal questions to check?

Rules on testing, cannabis use, privacy, notice requirements, commercial driver licensing and discipline vary by state and sometimes by county. Federal rules may apply to certain drivers.

Do not copy a policy from another state. Talk to an employment attorney, your state labor agency or the U.S. Department of Labor before you rely on any testing or discipline plan.

Make a short list of questions for your attorney before the meeting: what testing is allowed, what notice is required, how to handle prescribed medicine and cannabis, and how to treat housing. Bringing questions saves time and money.

How do you talk about prescription medicine?

Many workers take prescribed medicine safely. The goal is not to pry. Invite anyone who is told by a doctor or pharmacist that a medicine may affect driving or machine use to tell a supervisor only that they need a lighter task.

Respect privacy. A supervisor does not need to know a diagnosis, only that a task change is needed for a while.

What should a supervisor do if someone seems impaired?

Do not confront in front of others and do not let the person keep operating equipment or driving. Move calmly, separate the person from hazards and arrange a safe ride. If there is any medical emergency, call 911.

Follow the steps in your written policy and document what you saw in plain, factual terms. Avoid guessing about causes.

Keep a simple checklist for supervisors so that the response is the same every time. A checklist reduces the chance of an emotional reaction that makes a hard situation worse for everyone involved.

How do you roll out the policy fairly?

Share the written policy with every worker, including family and seasonal staff, and give people a chance to ask questions. Offer it in the languages your workers speak and keep a signed or acknowledged copy on file as your attorney advises.

Apply the policy the same way to every person. Uneven enforcement damages trust and can create legal trouble. Document concerns and actions in neutral, factual language.

Share the policy at a time when no one is in trouble, such as at orientation or a spring meeting. People hear it differently when it is explained as a safety measure rather than a response to a particular incident.

How can the policy support people who need help?

Substance use is a health issue as well as a work issue. Tell workers how to reach confidential help, such as a doctor, a local clinic or a community counseling service. Information about treatment options is available from the official sites listed below.

For stress, depression or crisis, people in the US can call or text 988. Make clear that asking for help early will be treated with respect.

• Post local support contacts in the shop or break area
• Remind everyone that asking for help is not a firing offense by itself unless your policy and law say otherwise
