Which of the following is not an example of misconduct that can deny unemployment benefits?

Refusal to work overtime is generally not considered a form of misconduct that would typically lead to the denial of unemployment benefits. In many employment contexts, employees are entitled to set reasonable limits on their work hours unless they have expressly agreed to work overtime as part of their employment conditions. If an employee refuses overtime, it does not inherently reflect willful or reckless disregard for their employer’s interests, which is often a key consideration in determining misconduct.

In contrast, drug abuse, abusive behavior, and insubordination can all be considered forms of misconduct. These behaviors can indicate a serious breach of the expected standards of conduct in the workplace, which can contribute to an employer's decision to terminate an employee. Such actions may be deemed as demonstrating a lack of respect or responsibility, leading to a justified denial of unemployment benefits since they relate directly to the individual’s ability to fulfill their job duties in a professional manner.

Consequently, the refusal to work overtime often lacks the same weight of negative implications associated with the other examples, making it the answer that does not align with misconduct leading to unemployment benefit denial.
