Answer:
D. Improve task significance.
C. Knowledge of the actual results of work activities.
Explanation:
1. In order to address this issue you should focus on improving task significance. Doing so will increase employee motivation as they will begin actually seeing that their work is important. Being able to visualize the consequences that your work has on others or in general is incredibly motivating in a work environment as it provides purpose to the otherwise mundane tasks.
2. In this case, you would need to target a redesign of Knowledge of the actual results of work activities. Employees need to be able to visualize or atleast hear feedback of how they are performing. This feedback will allow them to adjust their actions/performance and improve upon it. Without this feedback there is no way for the employees to improve as they have no baseline of what is exceptional behavior if they do not have data or an example to compare their performance to.
