Up until recently, I was using the words job description and job posting interchangeably. They are two very different things. A job description is a technical document and it includes some high-level esoteric stuff, like competencies, abilities, and requirements. You cannot have a fair and equitable work environment unless you have a clear and specifically delineated job description. And well, a job posting is what you put on the Internet (or back in the “olden” days, in the newspaper).
