Answer:
C. Because union wages exceed nonunion wages, employees may be encouraged to work harder.
D. Unions may provide information to companies about how to improve operations and eliminate problems in the work environment.
Step-by-step explanation:
Workers' unions have been instrumental in ensuring that workers work in the environment that is safe and conducive. Not only that, the unions also ensure that the workers are remunerated fairly for their labor and services. Thus, the wages of the unioned workers are higher because unions bargain for the increase in the worker's wages.
Furthermore, the worker's union work hand in hand to exchange information about the conditions of the workers and how the companies can eliminate the potential problems that result in worker dissatisfaction. In addition, the unions protect workers from exploitation.
