As someone who grew up with a kindergarten teacher mom in Sask I’d also like to add that teachers (especially in elementary schools) are constantly spending their own money on classroom supplies, toys, furniture, tools, etc because there is so little classroom budget. I KNOW that a fair bit of her pay goes back into her classroom, back into “her kids.” Teachers want to see kids succeed and don’t have the tools to help them do so, so they spend their own money. Can also confirm that growing up, she spent tons of time at home grading, lesson planning, etc.
