This study aimed to explore the perceived characteristics of “bad” managers working within the hospitality industry. By employing a grounded theory approach, 72 hospitality employees were interviewed and asked to describe the attributes and behaviors of a current or past bad manager. In addition, the respondents were asked about the root cause/s of the undesirable qualities described in the study. The research findings identified six themes relating to the attributes of bad managers: unprofessional, autocratic management style, poor leadership skills, unethical, poor operational and technical skills, and poor decision and delegation skills. In addition, perceptions of the root causes of bad managers were categorized into four themes: company culture and structure, personal characteristics, unqualified, and tenure and comfort zone. This is one of the first studies in the hospitality field to address bad managers’ attributes and why and how managers became bad managers. Specific theoretical and practical implication are provided.
