The two main bases of employee discipline are: a. employee behavior and insubordination. b. insubordination and absenteeism. c. job performance and employee behavior. d. failure to improve after a negative job evaluation and absenteeism.

The correct answer is c. job performance and employee behavior. Employee discipline is a process of correcting an employee's actions or behaviors in the workplace. The two main bases of employee discipline are job performance and employee behavior. Job performance relates to how well an employee is performing their job duties and meeting the expectations set by their employer. If an employee is not meeting these expectations, they may be subject to disciplinary action. Employee behavior refers to actions or conduct that is acceptable/unacceptable in the workplace. This could include things like insubordination, harassment, or discrimination. If an employee exhibits inappropriate behavior, they may also be subject to disciplinary action. While absenteeism and failure to improve after a negative job evaluation are both potential reasons for disciplinary action, they are not the two main bases for employee discipline.
