Work Rat Shirts β€” Office & Business Rat Tees

Coffee-fueled, deadline-driven, running on 3% battery β€” the work rat is anyone who's ever survived a Monday. Original hand-drawn art for the working world.

Somewhere between the third cup of coffee and the fourth notification, work starts to feel less like a career and more like a survival sport. Our work & business rat collection exists for exactly that feeling — the burned-out, the boardroom-bound, and everyone running on fumes between meetings.

These designs are original hand-drawn artwork, not stock office clip art. You'll find a rat operating at 3% battery, hugging a battery pack like it's the last one on Earth, right alongside a sharp-dressed business rat clutching a coffee and a to-do list that's somehow gotten longer since lunch. It's workplace humor that doesn't punch down at anyone — just an honest, slightly chaotic look at what work actually feels like most days.

Wear one on casual Friday, gift one to the coworker who's clearly running on empty, or treat yourself after a week with way too many meetings that could've been an email. Every tee is a premium unisex fit made from Airlume combed and ring-spun cotton, DTG printed in black or white, sized XS to 5XL, and shipped free within the USA.

Are these shirts okay to wear to a casual office?

Yes — the humor is lighthearted and workplace-appropriate, perfect for casual Fridays or after-work wear.

Do you make matching shirts for a whole team?

Our designs come in a wide XS–5XL range, so a whole department or team can order matching sizes easily.

What's a good work-themed gift for a coworker?

The “Operating on 3%” design is a favorite for anyone who's visibly running on empty — it's an instant, relatable laugh.

What is a “work rat” shirt?

A work rat shirt is a funny, relatable tee for anyone deep in office life — the meetings, the deadlines, the inbox that never empties. Ours put an original hand-drawn rat character in that exact situation instead of using a generic corporate slogan.

What material are the shirts made from?

Every shirt is a premium unisex tee made from Airlume combed and ring-spun cotton, DTG (direct-to-garment) printed for a crisp, long-lasting finish. They're available in black or white, made with eco-friendly cotton, with a comfortable everyday fit — check the size chart before ordering.
