If the work is not done to the employer's liking, there will be no recompense even if you wear yourself out!
Good Man Wang began working as a laborer when he was seventeen. Whenever he started working at a new place, he would observe his employer closely and watch how the workers carried out their work. If his employer's courtyard was well-kept and everything was tidy, he knew that his employer would prefer things to be clean and orderly. This being the case, he would make certain to conduct himself in a spick-and-span manner. If in his employer's fields, the furrows were deep, the soil fertile and the manure abundant, then he knew he had a scrupulous employer, and he was never careless or hasty in working for him.
If the employer's yard were really cluttered, with things strewn all around, and you try to be neat and organized in your work, your employer will surely accuse you of procrastinating. If the employer's compost were littered about and his field were overgrown with weeds, then this employer is likely to be impetuous and to make his employees work in haste. If you try to be meticulous, he will complain that you are plodding.
It is said, "If the work is not done to the employer's liking, there will be no recompense even if you wear yourself out." Good Man Wang always took his employer's preferences into account, and consequently he was well-liked wherever he worked.
