Did Emily seek employment?

Miss Emily Grierson did have employment for a time, but the narrator says that about eight or ten years earlier, "she ceased giving china-painting lessons" in her home.
The narrator also recalls that the china-painting lessons went on for "a period of six or seven years." Emily Grierson had transformed one of the first-floor rooms in her home into a studio, and her students were the young girls of the genteel families.
Beyond the years as an instructor of a forgotten art for well-bred young women, Miss Emily apparently did not seek other employment. Presumably she had an inheritance, evidenced by the comings and goings of the servant who did her grocery shopping and her purchases for Homer Barron.
The inheritance must not have been extraordinarily generous, because her home is described in the opening paragraph as "an eyesore among eyesores" on a once-grand street in town.
