By Katrina | The Animated Teacher
Hey everyone, Katrina here. I want to talk about something that doesn’t get discussed enough in the teaching world: sick day guilt.
You know the feeling. You’re sick. Or you have a medical appointment, or a family thing that can’t be rescheduled. Or even a professional development day. And instead of just… dealing with it like a normal human being, you spend the night before writing a novel-length sub plan, leaving instructions for five different activities in case one doesn’t work, worrying about whether the class will behave, and feeling guilty for daring to take a day off.
It’s absurd. And it’s exhausting. And yet almost every teacher I know has been there.
I want to share what changed things for me — because once I solved the sub day problem, I genuinely stopped dreading it.
Where does the sick day guilt come from?
The truth is the guilt actually comes from a good place. We care. We care about our students, about their learning and their wellbeing. We don’t want to let them down. But it often means we put our own wellbeing and health second.
Unfortunately, this guilt also comes from knowing our class may not be covered by an adequate sub teacher. They may not have any background in our subject or know how to teach it.
Why Most Sub Plans Fail (and lead to sick day guilt)
Before I could fix the problem, I had to understand it.
The traditional sub plan usually looks something like this: a worksheet packet pulled from last year’s resources, a “watch this video and answer questions” segment that relies on the internet working, and a vague instruction to “keep them on task.” The sub has no context. The students know the sub has no context. And everyone checks out.
The three failure points are almost always the same:
The resource isn’t self-directing. A worksheet that requires prior teacher explanation to complete is useless in the hands of a sub who doesn’t know the content.
There’s no built-in accountability. If students can finish in ten minutes and there’s nothing compelling them to keep going, chaos fills the gap.
The work feels like busy work. Students can smell a “just fill the time” activity from a mile away, and they respond accordingly.
What a Good Sub Lesson Actually Looks Like
A good sub lesson has three qualities: it’s self-contained, it’s genuinely engaging (not just “nice to do”), and it ties directly back to curriculum content.
This is exactly what I had in mind when I developed my Sub Lesson Plans range. Each one is built to be walked into cold by a non-specialist teacher or a substitute. The instructions are embedded in the resource itself — not in a separate document that might get lost — so students are guided through the task without the sub needing to explain anything.
For middle school science especially, this is a game-changer. The sub doesn’t need to understand the nitrogen cycle to facilitate an activity that teaches the nitrogen cycle. They just need to say “open your laptops, here’s the link” or distribute a printable version.

The Digital Escape Room: My Secret Sub Weapon
Here’s the resource type that has genuinely saved me more times than I can count on a sub day: digital escape rooms.
I know I talk about escape rooms a lot. But on a sub day specifically? They are unbeatable. Here’s why.
Students receive a clear challenge — a mission to complete, a code to crack. The self-correcting format means the sub doesn’t need to mark anything or check answers in real time. If students get a wrong answer, the form tells them to try again. If they get it right, they advance. There’s a built-in incentive to stay focused, because students want to crack the next code.
The sub becomes a facilitator, not a content expert. And the academic rigour never drops, because the content itself is embedded in the puzzles.
My Science Skills Escape Room bundle is one of my most-used for sub days precisely because it works across different stages and topics — it’s focused on scientific thinking and skills rather than one specific unit, which makes it incredibly flexible. Great for when you’re not sure exactly where the class will be up to when you’re away for a sick day.
What to Leave in Your Emergency Sub Folder
Okay, practical time. Here’s what I now keep in my “emergency sub folder” — the one that means I can take a sick day without feeling like I’m abandoning my class.
For early in a unit: A digital escape room that introduces the topic through problem-solving. I often use this as a pre-teaching hook anyway, so it works perfectly when I’m not there to deliver explicit instruction.
For mid-unit consolidation: A reading comprehension activity paired with questions. My Science Reading Comprehension Worksheet Bundle is brilliant here — it’s curriculum-aligned, completely self-contained, and gives students something genuinely meaningful to work through independently.
For end of unit review: The Body Systems Crossword Bundle (or topic-specific crossword) works a treat for consolidation. Students think it’s easy. Their brains are doing serious retrieval work. Everyone wins.
For an unexpected “extra time” situation: I always have a few Early Finisher Activities printed and ready to go. The kind of tasks that a student who finishes early can pick up and get stuck into independently, without needing instructions.
The Lab Safety Problem on Sub Days
Here’s something I wish someone had told me earlier in my career: never leave a lab practical for a sub day. Even if it’s a simple activity, it’s not fair on the sub, it’s not fair on the students, and it creates WH&S liability that nobody wants to deal with.
What I do instead is leave the Lab Safety Posters activity in the sub folder for early in the year sub days. Students engage with the lab safety content — which is genuine curriculum — while the sub has something visual and structured to run the lesson around. The Bunsen Burner L11 editable FREE templates for teachersicence activity is also excellent for this — it’s a bit of fun, completely safe for a sub to facilitate, and actually builds the safety cul11 editable FREE templates for teachersture you need for the rest of the year.
Giving Yourself Permission to Take the Day
I want to end on something that isn’t about resources at all.
You are a person, not a martyr. You are allowed to be sick without the sick day guilt. You are allowed to have appointments, and personal days, and emergencies, and just-need-a-mental-health-break days. Taking care of yourself is not a failure of your professional responsibilities — it’s a prerequisite for being able to do your job well in the long run.
The reason I built such a robust library of sub-ready resources was not just to make sub days easier. It was to remove the guilt that was eating away at me every time I needed to take one. When I know my students are going to have a rigorous, engaging, well-structured lesson even without me — I can actually rest. Which means I come back better.
Your students need you at your best. And you can’t give your best when you’re running on empty.
So please: build your sub folder. Grab the resources. And take the day without the sick day guilt.
Happy teaching — and happy resting! 💙
