The Real Law of Supply and Demand for Substitute Teachers #1544981 (License: Personal Use)

In this satirical cartoon, a student asks her teacher, Mr. Muehling, about the economic principle of supply and demand, only for the substitute teacher to wryly note that for subs, it means working an extra hour during an extended school day with no added compensation. A small, sardonic figure adds the punchline: “What about the Law of ‘An hours pay for an hours work?’” The image critiques systemic inequities in educator pay structures using irony and visual storytelling.

This image is commonly used on advocacy sites, union blogs, or educational policy pages to highlight unfair labor practices affecting substitute teachers. It targets educators, policymakers, and concerned parents seeking to understand or reform compensation models in K-12 education.
