“He Was Escorted From The Building By A Cop”: 30 Terrible Things Substitute Teachers Did

Substitute teachers are the educational equivalent of a relief pitcher jogging in from the bullpen… except the bullpen is a parking lot,
the crowd is 32 seventh-graders, and someone has already hidden the dry-erase markers. Most substitutes are pros who keep learning moving
and students safe. But every school has heard the storiesthe days that went off the rails so hard they became legend.

This article is a reality check (with a sense of humor, because coping is a skill): 30 truly terrible things substitute teachers have done,
why these situations happen, and what schools, teachers, and families can do to prevent the next “please report to the office immediately”
moment. We’ll keep it grounded in real-world patterns reported across U.S. districts and news coveragewithout turning it into a panic parade.

Why Substitute Teaching Can Go Sideways (Fast)

1) Subbing is high-trust, high-chaos work

A substitute walks into a room where routines, relationships, and inside jokes already existthen has to run that system with limited context.
If the lesson plans are vague, the seating chart is missing, or the behavior expectations aren’t crystal clear, the substitute is forced to
improvise. Improvisation can be great in jazz. In a classroom? It depends on the day and the audience.

2) Shortages and “lowered barriers” can create risk if training doesn’t keep up

Many states and districts have tried to widen the substitute pipelinesometimes by reducing minimum requirements or creating fast-track options.
That can help fill classrooms, but it also raises the stakes for strong screening, orientation, and clear supervision structures. When systems
move quickly, gaps show up quickly.

3) The job invites two classic failures: over-control and under-control

When a substitute feels outmatched, they may clamp down too hard (yelling, humiliating, punishing) or go the other direction (shrugging,
free-for-all, “just watch a movie”). Both routes create classroom management problemsand in the worst cases, safety problems.

What Counts as “Terrible” (And What Doesn’t)

A substitute forgetting names? Normal. Mispronouncing “Nguyen” and then sincerely trying again? Also normal.
“Terrible” is behavior that puts students at risk, violates professional boundaries, or undermines basic school safety and trust.
The list below ranges from reckless incompetence to misconduct that can become criminal.

30 Terrible Things Substitute Teachers Have Done (And Why They’re Deal-Breakers)

A) Safety and Supervision Fails (1–5)

1. Left students unattendedbecause “they seemed fine.”
   Leaving a class unsupervised invites injuries, fights, bullying, and property damage. “Fine” can turn into “incident report” in 14 seconds.
2. Blocked students from accessing help.
   Denying bathroom requests as a power move, refusing nurse visits, or ignoring a student’s reported medical need can escalate into harm.
3. Ignored emergency procedures (or made up new ones).
   Fire drill? Lockdown? The correct move is to follow the posted protocolnot freestyle a “substitute edition” of safety.
4. Used unsafe physical “control.”
   Grabbing, yanking, or using force to “make a point” is a fast path to injuries, investigations, and potential criminal charges.
5. Let the room become a “supervised by vibes” situation.
   Turning your back for long stretches, staying glued to a laptop, or treating monitoring as optional creates predictable chaos.

B) Boundary Violations With Students (6–10)

6. Private messaging with students.
   Texting, DMing, Discord chatting, or “just following them back” blurs lines and raises serious safeguarding concerns.
7. Oversharing personal details like it’s a podcast confessional.
   Students aren’t your therapists, dating coaches, or memoir workshop. Keep it professional and age-appropriate.
8. Favoritism that turns into “special access.”
   Letting a student hang out alone with the sub, offering rides, or creating “friendship” dynamics is a bright red flag.
9. Flirting, sexual comments, or “jokes” that aren’t jokes.
   Even “I was kidding” can be harassment. A classroom is not a comedy club and minors can’t consent to adult attention.
10. Inappropriate photos or content on a personal phonevisible in class.
    Scrolling risky content where students can see it is unacceptable and can become a law-enforcement issue.

C) Discipline Disasters (11–15)

11. Yelling as a default management strategy.
    It escalates behavior and erodes authority. Students tune out the words and remember the volume.
12. Public humiliation (“Let’s read your grade out loud!”).
    Shaming students is a quick way to lose the roomand sometimes your job.
13. Collective punishment for individual behavior.
    “Nobody goes to lunch until I say so” can become unsafe and often violates school policy.
14. Power struggles over tiny things.
    Turning “put your hood down” into a 12-minute standoff derails instruction and hands the class the steering wheel.
15. Threats that you can’t (or shouldn’t) carry out.
    “I’ll expel all of you today” is not a plan. It’s theater. Students can smell bluff like spilled milk.

D) Instructional Faceplants (16–20)

16. “We’re watching a movie” with no educational purpose (or permission).
    Surprise screen time isn’t a lesson planespecially if the content isn’t vetted.
17. Teaching the wrong material confidently.
    The most dangerous kind of wrong is enthusiastic wrong. If you’re unsure, follow the plan or keep it skills-based.
18. Refusing to follow the teacher’s notes out of pride.
    “I have my own method” is fineuntil it breaks the classroom routine or contradicts school expectations.
19. Using “busywork” as punishment.
    Students can tell when an assignment exists to hurt their feelings. Learning should never be revenge.
20. Turning the day into a free-for-all because “it’s only one day.”
    One chaotic day can undo weeks of routine. The goal is continuity, not classroom anarchy tourism.

E) Professionalism Fails (21–25)

21. Showing up late and blaming traffic… in a town with one road.
    Kids notice. Staff notice. And the office has heard that excuse since 1998.
22. Sleeping, disappearing, or “taking a quick call” for 20 minutes.
    You’re supervising minors. This isn’t a co-working space.
23. Using sarcasm as a personality.
    “Nice job, genius” doesn’t build rapportit builds resentment (and sometimes parent emails).
24. Arguing with staff like it’s a reality TV reunion.
    If a paraeducator, teacher next door, or admin gives direction, the professional response is cooperation.
25. Violating basic rules: phones, confidentiality, or student records.
    Taking photos, gossiping about students, or sharing private info is a trust breach and can have legal implications.

F) The “How Is This Real?” Category (26–30)

26. Stealing from the classroom.
    Taking cash from a fundraiser jar, supplies, or student property isn’t “borrowing.” It’s theft.
27. Coming to school impaired (alcohol or drugs).
    Safety risk, immediate removal, and often law enforcement involvement. Full stop.
28. Using physical violence to “restore order.”
    Hitting or pushing students crosses a hard line and can lead to arrest, termination, and lawsuits.
29. Engaging in sexual misconduct or grooming behavior.
    This is the most severe category: it harms students and triggers criminal investigations and lifelong consequences.
30. The headline moment: “Escorted from the building by a cop.”
    This is what happens when misconduct meets documentation: student reports, witness statements, camera footage,
    and a school resource officer walking someone out. It’s rarebut it’s the nightmare scenario that policies are built to prevent.

Why These Incidents Happen (Without Excusing Them)

Systems factors that can set a substitute up to fail

• Inadequate onboarding: No quick orientation to routines, behavior supports, technology, or emergency procedures.
• Thin lesson plans: If the plan is “Chapter 7, good luck,” the day becomes improv comedyminus the laughs.
• Unclear escalation paths: Subs need to know who to call, how to document, and what to do in the first 60 seconds of a problem.
• Shortages: When districts struggle to staff, there can be pressure to fill jobs quickly. That’s exactly when screening and training must stay strong.

Individual choices that turn bad days into dangerous days

• Ego: Refusing guidance because “I’ve got this,” even when you don’t.
• Poor boundaries: Trying to be a friend, a flirt, or a hero instead of a responsible adult.
• Stress reactions: Yelling, humiliating, or escalating power struggles when calm structure would work better.

How Schools Can Prevent the Worst Substitute Teacher Misconduct

1) Screen carefullyand consistently

Background checks and fingerprinting requirements vary by state and role, but the principle is the same:
adults with direct, unsupervised access to students must be vetted thoroughly. District handbooks often spell out
fingerprint/background check expectations and employment conditions, and state education agencies publish guidance on
fingerprinting procedures and requirements.

2) Provide a “first 15 minutes” substitute orientation that actually helps

A short, repeatable orientation can prevent long, regrettable days. The essentials:
where to get help, how to call the office, discipline procedures, emergency protocols, technology basics,
and the school’s non-negotiable boundaries (no private student contact, no unsupervised situations, no photos).

3) Equip substitutes with classroom management tools

Substitutes aren’t mind-readers; they need simple, portable strategies: clear rules, consistent consequences,
positive reinforcement, active supervision (moving around the room), and engagement routines that reduce misbehavior.
Many training guides emphasize that structure beats volumeevery time.

4) Create better support in the building

Pair substitutes with a nearby “buddy teacher,” make paraeducator roles clear, and ensure administrators respond quickly
to calls for help. When a substitute feels supported, they’re less likely to panic, overreact, or abandon the plan.

How Teachers Can Set Substitutes Up for Success (And Protect Students)

• Leave explicit procedures: entry routines, phone policy, bathroom policy, how to handle early finishers.
• Over-prepare materials: extra work prevents “dead time,” which is where chaos breeds.
• Assign student helpers thoughtfully: reliable leaders plus a student who benefits from responsibility can stabilize the room.
• Make “call the office” normal: the substitute should never feel ashamed to ask for support.

What Students and Parents Can Do If Something Feels Wrong

Students should know: reporting isn’t “snitching” when safety is involved. Parents should encourage kids to document basics
(what happened, when, who else was present) and report concerns promptly to the school. Administrators can’t respond to what
they don’t know. And many serious cases begin with a student or staff member speaking up.

Conclusion: Most Subs Are GoodBut Systems Must Plan for the Bad

Substitute teachers keep schools running. They’re often underpaid, under-prepped, and asked to manage a room that already has its own ecosystem.
That’s exactly why districts need strong vetting, clear onboarding, and real-time support. Because the cost of “we’ll figure it out later” is too high
when the people in the room are kids.

Extra: of Classroom Experiences Related to Terrible Substitute Days

Below are composite experiencespatterns repeatedly described by students, teachers, and administratorswritten as scenes you might recognize.
They’re not about one specific school or person. They’re the “this is why we have policies” moments.

Scene 1: The Vanishing Lesson Plan. The substitute arrives to find a single sticky note that says, “Math worksheet in the bin.”
The bin is empty. The students sense uncertainty like sharks sense a drop of blood in the water, except the sharks have Chromebooks. A few kids
volunteer “helpful” information: “Our teacher always lets us sit wherever we want,” and, “We’re allowed to be on our phones for research.” The sub
tries to be flexible, which students interpret as “rules are negotiable.” By second period, the room is loud, the work is half-done, and the substitute
is stuck choosing between yelling (which escalates) or surrender (which also escalates). This is how a normal day turns into a discipline day.

Scene 2: The Power Struggle Olympics. One student refuses to take off a hood. The substitute makes it the hill to die on.
Five minutes later, the hood is no longer the issue. The issue is prideadult pride versus teenage pridewhile everyone else watches the competition.
The class starts taking sides. A small conflict becomes the day’s main event. The most experienced teachers will tell you: pick your battles, then pick
smaller ones. The goal is learning and safety, not winning a debate against a 14-year-old with an audience.

Scene 3: The Boundary Blur. A substitute tries to build rapport by being “the cool adult.” They tell stories that are too personal,
laugh a little too hard at edgy jokes, and start “checking in” with a student who seems lonelyalone, in the hallway, where nobody can see.
Nothing about it feels dramatic in the moment, which is exactly why it’s dangerous. Healthy boundaries look boring: open doors, public conversations,
clear limits, and consistent rules. Boring is good when you’re protecting kids.

Scene 4: The Phone Problem. The substitute is glued to a phone, not even for anything scandalousjust endless scrolling.
Students notice immediately. The room’s energy shifts. If the adult isn’t watching, students push limits. A paper ball flies. Someone walks out.
Two kids start filming. The substitute looks up only when the noise gets loud enough to break through the algorithm. This is how supervision fails:
not with villainy, but with distraction.

Scene 5: The Save. The best part is that disaster isn’t inevitable. In a parallel version of the same day, the substitute starts with
three sentences: “Hi, I’m Ms. Carter. Here’s the plan. Here’s what we do when we finish.” They write the agenda, set one or two simple rules, and move
around the room. They use positive reinforcementcalling out what’s going rightand they ask for help early if a situation feels off. The class still tests
boundaries, because that’s what students do, but the room stays steady. The day ends with learning intact and everyone’s dignity still standing. The difference
isn’t magic. It’s preparation, boundaries, and support.
