A single incident of which misconduct could be grounds for dismissal?

• A. Sexual harassment
• B. Tardiness
• C. Minor dress code violation
• D. Noise complaints

Answer: (A)

The key idea is that some misconduct is so serious that a single incident can justify dismissal, because it breaches the employee’s fundamental duties and violates rights protected by workplace policy and law. Sexual harassment falls into this category. It directly harms another person, creates a hostile or unsafe work environment, and typically contravenes anti-discrimination protections and employer zero‑tolerance policies. Because of its potential to cause immediate harm and violate the employer’s duty to provide a respectful workplace, a single incident can constitute just cause for termination.

By contrast, the other examples are generally viewed as less severe on a one‑off basis. Tardiness, a minor dress code violation, or a single noise complaint are typically addressed through warnings or corrective actions, unless they occur repetitively or with aggravating factors. They do not inherently undermine the employment relationship to the same degree as harassment, which is why they usually don’t justify dismissal after a single incident.
