What does Harry do for a living?

Harry is one of Eveline's two brothers. He's a very minor character in the story, and we never actually encounter him at any time. We only know about him through the narrator's description of Eveline's memories. For instance, we discover that, when he was younger, Harry was regularly subjected to violence by his father, as indeed was Ernest, Eveline's other brother, now departed.
Harry has also left the family home, but not quite in the same way. He works in the church decorating business, and often travels up and down the country as part of his job. His absence from the family home makes Eveline feel alone, that she's not adequately protected from her father. Indeed, her father is becoming increasingly threatening towards her. Yet, despite this, and her constant toiling away as a skivvy at home, she describes her life as not "wholly undesirable." This somewhat ambiguous attitude foreshadows the most important event in the story—the sudden decision that Eveline will make concerning her future as she stands on the quayside.
