Written 101 years ago, "The Job" is, to me, a book that probably needs hardcore footnotes to help place it in a more specific context. There are two things going on here that are somewhat foreign to me. One is the sociological context, whereby the heroine, Una Golden rises from a New York stenographer to a 'business woman'. Lewis presents her struggles in a male-dominated world in very black and white terms as Una does anything-but claw her way to the top. Her encounters with men and bosses, which we would now consider cliche, were probably very institutional at the time. So, readers must be willing to deal with serial insults and putdowns so that Lewis can get his point across in a not so subtle fashion.
The second is the literary context. Needless to say, a book of this age if filled with many cliches and old-fashioned argot that sounds alien today. Furthermore, I suspect that Lewis was bound by certain laws or mores of the time that causes much of the conflict in the book to seem very sugary when he wanted to pull out his knife and go for the throat.
For most of the book, I actually did not care much for Una and much of her self-imposed weakness. But, as she learns her way about the man's world of business, she becomes more interesting and likable. Most of this occurs about two-thirds of the way through. While the end is very satisfying, the last page seems like Lewis, who was not as emboldened as he later would be in his career, is conforming to literary devices of the day.
If you are a big Lewis fan, like I am, I do recommend "The Job". While not his best, most ever-lasting novels, it is far from his worst.
