Teaching is a very important job that is often very long hours, and I appreciate the work you are doing. I am also well aware that teachers tend to make less than other professions that require a similar level of education.
However, having compensation that is relatively less than other professionals does not mean you are objectively low-paid compared to the general public. Last time I looked, MA teachers were in the top 5 nationally for pay. While I don't know where you teach, and those in affluent eastern suburbs undoubtably make more than those in tiny rural districts in the western part of the state (with corresponding cost of living differences), the overall MA teacher's salary is middle class. I'm not sure why you deserve discounts more than the general public, especially when the general public includes support staff like aides, bus drivers, secretaries, and cafeteria workers, who all make far less than teachers, are tied to the same vacation schedule, and don't qualify for any special discounts.
In general, those in "helping" careers - teachers, nurses, social workers, etc. - are expected to be well educated, work long hours, and be satisfied with smaller paychecks than those in revenue-generating professions (finance, marketing, etc.). It sucks, and I get it. I'm a nurse and I used to be a public school teacher in CT, so similar pay and expectations to you. I understand feeling like what we do is not valued as it should be. I understand how demoralizing it is when your profession is a politician's punching bag. But I have never felt like my compensation was so low that I needed or deserved special discounts. Sure, I'm happy to take them when they come, but I don't think teachers or nurses or members of any other profession are entitled to them.
Since you're asking on another thread how to score the limited edition Minnie Mouse ears and lounge fly purses, it seems you're doing okay financially. I realize this is the internet, so I want to clarify that this post isn't meant to be snarky. Just pointing out how you might want to take a step back, and look at your financial status in comparison to those who aren't doing as well as you, and don't get special discounts either.
