Answer:
A) carefully select workers according to their abilities and give workers training.
Most likely, these workers are decreasing their productivity through the means of soldiering. In other words, it means that they would follow the productivity pattern of the least productive worker, since they all get the same benefits (or the lack of a mutual benefit - tuition reimbursement program).
In order to combat this negative practice, Arthur should select workers with robust, high-quality abilities and provide them with a training and development program. This way they will become ultimately productive, while the cost-cutting corporate policy will be kept.
