Preventing ageism is more about taking the lead and applying standards that are right for everyone in your community. Here's an example of equal opportunity standards applied to jobs in the USA; this was taken from an ESL job announcement for the Providence Public Library in Providence, Rhode Island, USA:

Equal Opportunity
In order to provide equal employment and advancement opportunities to all individuals, employment decisions at the Providence Public Library are based on merit, qualifications, and abilities. PPL is committed to a policy of non-discrimination and equal opportunity for all employees and qualified applicants without regard to race, color, religion, gender, sex (including pregnancy, childbirth or medical or common conditions related to pregnancy or childbirth), sexual orientation, gender identity, gender expression, marital status, familial status, national origin, ancestry, age (40 and above), disability, veteran status, military service, application for military service, genetic information, receipt of free medical care, or any other characteristic protected under applicable law. PPL will make reasonable accommodations for qualified individuals with known disabilities, in accordance with applicable law.

No discrimination against people age 40 and above! Ajarn.com should have this standard, because ageism in Thailand is mired in the culture or in Thai society. Someone has to take the lead to prevent ageism in Thailand! For years, ajarn.com, eslcafe.com and other ESL job websites have carried ads promoting or supporting ageism. It's time for ajarn.com to have better standards. Lead the way!

Teachers in their 40's, 50's, 60's, 70's and beyond can be wiser and have more experience. Very importantly, the older and wiser you are, the more likely you are to have genuine compassion for students... especially important with all the possible roadblocks students can encounter, learning a second language!
