Spot That Red Flag! Substance Abuse Suspicion Protocols for Managers

Spotting substance issues is not about guesswork, it’s about sharp eyes and a sharper plan.

Substance abuse in the workplace isn’t just a buzzkill, it’s a safety, productivity, and liability nightmare. Reasonable suspicion training is your toolkit for spotting red flags and stepping in before things spiral. Ready to become the office Sherlock? Let’s dive in.

Recognizing the signs is step one, documenting like a pro is step two.

Red Flags You Shouldn’t Ignore

• Physical: Slurred speech, bloodshot eyes, random stumbles that aren’t just clumsiness.
• Behavioral: Mood swings, missed deadlines, showing up late, or not at all.
• Psychological: Confusion, forgetfulness, or reacting to stuff that isn’t there.

What the Feds Say

The FMCSA (that’s the Federal Motor Carrier Safety Administration) lays out when you can test. So no, it’s not a free-for-all, but it does have your back when someone’s acting sketchy on the clock.

Here’s Your Game Plan

• Know the rules: Understand company policies and make sure everyone else does too.
• Play it legal: Union contracts and employee rights matter, don’t skip the fine print.
• Watch and note: Document behavior changes like a boss.
• Build a case: Records are your receipts when things get tricky.
• Act smart: Present the evidence and offer support, not judgment.

If you’re gonna bring it up, do it right or don’t do it at all.

Your Move When Things Look Off

• Pause their shift: Don’t let them operate machinery while smelling like a brewery.
• Keep it private: Call a meeting in a neutral space and keep it professional.
• Explain the test: Lay out your concerns clearly and without drama.

Ask the Big Questions

• Is someone’s safety (including theirs) at risk?
• What exact behavior are you observing?
• Do you need expert backup or immediate intervention?

It’s not punishment, it’s a wake-up call with a support system.

How to Refer Without Sounding Like a Warden

• Know your options: Point them toward help that actually works.
• Insurance check: See what coverage they’ve got before sending them anywhere.
• Stay compliant: Especially if you’re in DOT territory, follow protocol with a qualified Substance Abuse Pro.

Strike the Balance

You’re not a therapist, but you are a leader. Lead with empathy, back it with policy, and keep things consistent.

Documentation isn’t optional, it’s your best legal armor.

Tips for Writing It Right

• Be precise: Time, date, behavior. Skip the drama, stick to facts.
• Double it up: Two observers are better than one. Get backup.
• Get real: Include examples that actually happened, not vibes or hunches.

What a Real-Life Case Looks Like

Employee shows up smelling like vodka, slurs through a meeting, and nearly naps at their desk. Supervisor A spots it, tags in Supervisor B, and HR gets looped in. Documented. Handled. By the book.

If They Refuse to Test

Treat it like a positive. Get them home safely, file the paperwork, and stick to your protocol.
