Answer:
Hi!
The answer would be more-less. So the sentence would look like this: More productive workers are likely to be of greater value and earn higher wages than less productive workers.
Step-by-step explanation:
Like we know, the word productive can describe a person's capability to do a lot of work or can refer to anything that produces a lot. A worker that is productive, hence, that can do a lot of work, is more valuable than a worker who is less productive, hence, gets less work done in the same amount of time. This is because the productive worker can get through tasks faster and consequently bring more money and clients than a worker who is not as productive. Because the company values a worker who brings more clients, they are willing to pay productive workers more money so they can be satisfied with their job and stay with the current compamy.
