Which of the following is considered a major infraction in corporate policy?

Insubordination is considered a major infraction in corporate policy because it directly undermines the authority of supervisors and disrupts the organizational hierarchy. This behavior can severely affect workplace dynamics, leading to decreased morale, productivity, and overall effectiveness. Insubordination challenges the command structure essential for managing employees and fulfilling business objectives.

The other behaviors listed, while still potentially problematic, typically do not carry the same weight in terms of organizational impact. Excessive breaks may indicate a disregard for productivity but usually can be addressed with coaching or reminders. Being late to work may reflect issues with time management or personal circumstances that can often be remedied with flexible solutions. Ignoring company emails could signify communication issues, but this too can usually be resolved through gentle reminders or adjustments in protocols. In contrast, indiscipline in relation to authority poses significant challenges that require more serious attention, thus categorizing it as a major infraction.
