The hidden ethical costs of workaholism have been highlighted in a recent study led by Aston University and University of Leipzig scholars.

Workaholism is an inner pressure to working, that provides a sense of fulfillment but can lead to physical and , relationship issues and burnout.

The study, in the Journal of Organizational Behavior, showed that it can interfere with moral self-regulation and subsequent ethical behavior, particularly in organizations that prioritize bottom-line results and self-interest.

An international team of researchers, led by Professor Roberta Fida (Aston University) and Dr. Michael Knoll (University of Leipzig) conducted two surveys to study workplace behavior. They gathered responses from employees in Italy (505 people) and the UK (1,046 people) over three different points in time.

Their findings show that being a workaholic can cause people to become less engaged with their moral values. This makes them less likely to speak up about ethical problems they notice at work and more likely to stay silent, even when they see something wrong.

The research draws on Bandura's social cognitive theory of morality, which suggests that moral behavior is regulated by personal standards and . The researchers found that moral disengagement acts as a critical mediator between workaholism and employee silence or moral voice. Workaholism increases tendencies to morally disengage which, in turn, led to less moral voice and more employee silence.

Another finding surrounded the role of the organizational context. The second study revealed that a perceived climate of , where employees believe that individual gain is prioritized over other values such as norms or collective welfare, amplifies the negative effects of workaholism. In these environments, workaholics were even more prone to morally disengage, further diminishing their likelihood of addressing .

Roberta Fida, professor of organizational behavior and at Aston University, said, "We often think of workaholism as a personal struggle or even a badge of dedication, but our research shows it has far-reaching consequences.

"Workaholics, focused intensely on task completion and personal achievement, tend to disengage from their moral standards. This leads them to rationalize silence in the face of unethical practices, which can preserve behaviors and practices that are potentially damaging to organizations and society at large.

"Our findings highlight the critical need for organizations to rethink their workplace cultures, particularly in sectors where bottom-line mentalities dominate. When workaholism and a self-interested culture converge, the result isn't just burnout - it's a systemic erosion of ethical standards."

Dr. Michael Knoll said, "Workaholics justify withholding their voice by convincing themselves that their silence is harmless or justified as they need to prioritize finishing their tasks.

"But by doing so, they fail to address pressing organizational issues such as safety risks, unethical leadership, or inefficiencies that affect their colleagues and stakeholders.

"By normalizing silence and neglecting ethical concerns, organizations risk perpetuating harm to employees, stakeholders, and society. It's not just about individual well-being—it's about organizational sustainability.

"Employers need to move beyond seeing long hours and over-dedication as signs of commitment. Instead, they should foster an that rewards ethical behavior, encourages moral voice, and reduces pressures that lead to excessive working."
