Pluralizing with an apostrophe or not using quotation marks are even common with people who have English as a first language, and are signs of discomfort or lack of practice with English writing, which could be the result of dyslexia, English as an eighth language, or any other reason. Could even be stupidity, but when the ideas are coherent, to jump to that just seems to be a way to feel superior to someone.
Seemed like an intelligent enough comment to me, even though I would extend it to the reading comprehension that the author of the subject of this thread must lack to fail a 10th grade reading test with 62%, then further extend it to become a belligerent attack on management in general. The school boards in America are still debating evolution every single year. I add, of course, that school boards have nothing to do with teacher's unions, and break them more often than they support them.
I wish you luck in your struggle.
