ABSTRACT
Background and statement of the problem: Recognizing that organizations are under pressure to
increase workplace safety, this paper develops an integrative leadership model that informs new
theory identifying how leader behaviours enhance workplace safety behaviour. The paper
highlights direct and indirect relationships among transformational leadership, employees’ trust in
leaders, empowering leadership and employees’ safety behaviours. Research methodology and
data: The paper follows a rigorous, systematic review of published studies (1985-2017)
representing the literature addressing transformational leadership and safety behaviours, and the
moderation roles of empowering leadership and trust in leaders in the transformational leadership
and– safety behaviours relationship. The paper relied extensively on computerized keyword
searches in the main business source databases of EBSCOhost, Emerald, ProQuest, ScienceDirect
and SpringerLink. Research findings: The systematic review leads to a credible conceptual
framework that elucidates the relationship between transformational leadership, empowering
leadership, employees’ trust in leadership and workplace safety behaviours. Consequently, the
framework advances theories on effective leader behaviour, employees’ trust in leaders and safety
behaviours. Further, the framework assists with unpacking various underlying mechanisms through
which leadership directly and indirectly influences employee safety behaviours within the
manufacturing sector. In that regard, the paper argues that trust in leaders, and empowering leader
behaviours, both moderate the relationship between leadership and employees’ safety behaviours.
Policy implications: The conceptual framework provides the impetus for a behaviour-oriented
approach to workplace safety research, with the potential to generate actionable knowledge to
manage accidents and injuries in the workplace. The framework can be utilized by organizations
when executing organizational design interventions so as to engender and shape organizational
climate and culture of trust. The framework advocates empowering leadership behaviours which
could support employees to raise organization-related safety issues.

INTRODUCTION
The global concern for workplace safety, particularly in the manufacturing sector of most
countries, emanates from a real concern relating to the ergonomic and psychosocial risks
confronting employees in their daily job activities (Aryee & Hsiung, 2016; Jiang &
Probost, 2016; Nielsen et al., 2017; Pilbeam et al., 2016; Willis et al., 2017). Globally,
workers have lost their lives in work-related accidents, with the manufacturing sector
being amongst the top four sectors reporting high numbers of worker fatalities and being
consistently among the top few industries with the highest number of serious claims (Safe
Work Australia, 2015). As such, organizations are now focusing on the relevant human
factors which contribute to workplace safety (Clarke, 2013; Jiang & Probost, 2016;
Mullen et al., 2017; Nahrgang et al., 2011). So important is the issue of safety-related
outcomes and safety behaviours that businesses and researchers seek to understand the
role played by frontline employees in enhancing workplace safety (Mullen et al., 2017;
Sheehan et al., 2016; Smith et al., 2016). Given their status within teams and
organizations, it is plausible that supervisors could promote and boost the uptake of
safety related policies and programs within their workplaces. This is vital given that their
message of safety is likely to enhance their followers’ perception of more support
available from organizational leadership. Notably, the relationship between effective
forms of leadership and productive employee behaviour can be characterized as complex
and requiring further clarification. For example, some studies have associated
transformational leadership with employee trust (Burke et al., 2007; Dirks & Ferrin,
2002; Zhu & Akhtar, 2014). Other studies have associated empowering leadership
(Amundsen & Martinsen, 2014, 2015) with employee self-efficacy, job satisfaction, work
effort, and creativity. Surprisingly, there is a lack of understanding of the combined
effects of transformational and empowering leadership on safety behaviour, and it is vital
that a thorough literature review is undertaken to reconcile and collate all findings from
these disparate studies in a literature review which provides a clearer picture of how
effective forms of leadership directly and indirectly influence safety behaviour at the
workplace. Therefore, the overarching goal of this review is to develop a conceptual
framework generated from a systematic analysis of the literature addressing
transformational leadership, safety behaviours, and the moderating roles of trust in
management and empowering leadership. Specifically, this review has three main
objectives. First, it analyses previous studies to provide greater clarity in the potential
link between leadership and safety behaviours within the manufacturing sector. This
culminates in a new conceptual model (framework) utilizing the transformational
leadership lens to assess how leadership is associated with safety behaviours. Second, the
review examines the moderating roles of trust in leadership and empowering leadership
in the transformational leadership – safety behaviours relationship. Lastly, the review
puts forward feasible research propositions based on the conceptual model to help clarify
leadership – safety behaviours relationship. In the next section, the review describes the
research methodology, followed by a discussion of workplace safety.

RESEARCH METHODOLOGY
The systematic literature review followed a rigorous, in-depth analysis of the extant
literature, focusing on published studies representing the literature on transformational
leadership, trust in leaders, empowering leadership and safety behaviours. The literature
reviewed comprised of publications published between 1985 and 2017. Further, the
review relied on computerized keyword searches in the main business source databases of
EBSCOhost, Emerald, ProQuest, ScienceDirect and SpringerLink.
UNDERSTANDING WORKPLACE SAFETY
Organizations take great precautions to eradicate workplace accidents and injuries as they
undermine workplace safety, and could lead to individual, team, and organizational
consequences impacting on work performance outcomes (Battaglia et al., 2015; Sheehan
et al., 2016). This is necessitated by the need for organizations to proactively detect
unsafe behaviours and then initiate processes that prevent workplace accidents, while
engendering safety behaviours. Griffin and Neal (2000) describe employee safety
behaviour in terms of safety compliance and safety participation. Safety compliance
behaviour is demonstrated by the act of adhering to the established safety procedures and
policies, while safety participation behaviour contains those behaviours related to the
contribution to a safer and better work environment (Griffin & Neal, 2000). Other
research on safety issues within organizations has employed two approaches (DeJoy,
2005). The first approach, the behaviour-based safety approach, focuses on the
identification and modification of critical safety behaviors that relate to workplace
injuries and losses. Thus, tracking safety behaviour leads to appropriate interventions and
consequently influencing job performance. The second approach, safety culture approach,
focuses on molding a safety culture within organizations, and how that impacts safety
behaviours and safety program effectiveness (DeJoy, 2005). Recently, the two
approaches have been merged, as it they both denote a strategic role of organizational
leaders as they promote an ongoing, systematic approach to managing safety (DeJoy,
2005). Consequently, transformational leadership has been related to safety behaviour,
safety culture and safety climate (Mullen et al., 2017; Sheehan et al., 2016; Smith et al.,
2016; Zohar, 2010).
TRANSFORMATIONAL LEADERSHIP AS AN
EFFECTIVE FORM OF LEADERSHIP
Bass (1985) describes transformational leaders as those motivating their followers to
move beyond their individual self-interests for the good of the group, organization, and
society. They do this by exhibiting the following characteristics: idealized influence;
inspirational motivation; intellectual stimulation; and, individualized consideration.
Through idealized influence leadership, leaders behave in ways that make them role
models for their followers, putting the followers’ needs above their own personal needs
and sharing risks with followers. Through inspirational motivation, leaders behave in
ways that motivate and inspire their followers by providing meaning and challenge to
their followers’ work. Through intellectual stimulation, leaders encourage their followers

260
to be innovative and creative by questioning assumptions, reframing problems, and
approaching old situations in new ways. Finally, individually considerate leaders pay
special attention to each individual’s need for achievement and growth by acting as coach
or mentor. Previously, transformational leadership has been related to outcomes such as
profitability, business unit performance, employee satisfaction with leadership, employee
performance, and organizational commitment (Afsar et al., 2014). Due to its ability to
empower employees, transformational leadership has also been likened to another form
of effective leadership, that of empowering leadership (Spreitzer, 1995, 2008).
EMPOWERING EMPLOYEES THROUGH LEADERSHIP
Spreitzer (1995, p. 1443) describes empowerment in terms of ‘increased intrinsic task
motivation manifested in a set of four cognitions reflecting an individual’s orientation to
his or her work role: meaning, competence…self-determination, and impact’. Further,
empowerment relates to management practices geared towards the delegation of power
from supervisors to highly skilled and knowledgeable subordinates (Spreitzer, 1995,
2008). Thus, empowering leadership underscores the development of follower self-
management or self-leadership skills (Manz & Sims, 1987), and influences employees’
job satisfaction, work effort, and creativity (Amundsen & Martinsen, 2014, 2015). In a
workplace safety situation, leaders encourage employee empowerment and employee
involvement in decision making about occupational health and safety, while also
emboldening employees to be responsible for their own safety (Nahrgang et al., 2011;
Zohar, 2010).
RELATING LEADERSHIP TO EMPLOYEES’ SAFETY BEHAVIOR
Leader behavior that is characterized by trust, confidence, recognition, and feedback
could enhance workplace safety, and the well-being of employees (Clarke, 2013; Mullen
et al., 2017; Sheehan et al., 2016; Smith et al., 2016). Indeed, leaders with a commitment
to safety and those that encourage the involvement of their subordinate on safety related
issues are likely to achieve more open communication and engagement from their
subordinates regarding safety behaviors (Nahrgang et al., 2011). Further,
transformational leadership put in place necessary standards that amplify the importance
of safety to their employees’ jobs (Christian et al., 2009). Within the manufacturing
sector, transformational leaders utilize manufacturing strategy as a tool to enhance
operational performance (Birasnav, 2014). They also focus on employees’ future growth
and development, through inspirational motivation, individualized consideration,
intellectual stimulation, and idealized influence. Transformational leaders effectively
communicate their safety priorities, which in turn positively influence employee
perception of priority of safety, and employee perceptions of safety climate and employee
safety behavior (Clarke, 2013; Mullen et al., 2017). Therefore, in our proposed model
shown on Figure 1 below, we envisage a direct relationship between transformational
leadership and safety behaviors (both safety compliance behavior and safety participation
behavior). Thus,

261
Proposition 1a: Transformational leadership is positively associated with safety
compliance behavior.
Proposition 1b: Transformational leadership is positively associated with safety
participation behavior.
TRUST AND ITS IMPACT ON LEADER EFFECTIVENESS
AND SAFETY BEHAVIOR
Trust has been conceptualized as ‘a psychological state comprising of the intention to
accept vulnerability based upon positive expectations of the intentions or behavior of
another’ (Rousseau et al., 1998, p. 395). Research findings link trust to leader
effectiveness and indicate that trust impacts organizational citizenship behaviors (OCBs),
job performance, job satisfaction, organizational commitment, intent to quit,
organizational justice, psychological contracts, effective communication, conflict
management, and goal commitment (Burke et al., 2007; Dirks & Ferrin, 2002; Dirks &
Skarlicki, 2004). Burke et al., (2007, p.610) propose that organizational, relational, and
individual characteristics are the main antecedents for trust in leader, and that the
relational aspect encompasses ‘behavioral consistency, behavioral integrity, sharing and
delegation of control, communication, and demonstration of concern’.
Studies on trust in leaders indicate that employees choose to trust their leader if
they have positive expectations of the leaders’ safety intentions and behaviour (Conchie
& Donald, 2009). Consequently, trust in leadership could strengthen the followers’
willingness to follow their leader’s guidance on safety issues and programs within the
organization, and the followers’ perceptions of the leader behaviour towards safety

(Conchie & Donald, 2009). Further, the leaders’ commitment to safety influences safety-
specific trust, which in turn moderates the leader-member exchange and subordinate’s
safety behaviour (Conchie & Donald, 2009; Hofmann et al., 2003). Thus, trust in
leadership plays an indirect role in the leadership-safety behaviour relationship. It is
expected that high trust environments will increase the employee’s cooperation and
commitment to the organization, and that employees who operate in high trust conditions
will more likely engage in safety behaviour. As shown in Figure 1, we envisage a
situation where the more the followers trust their leaders, the more likely they will
engage in safety behaviours. Hence,
Proposition 2a: Trust in leaders moderates the relationship between
transformational leadership and safety compliance behavior.
Proposition 2b: Trust in leaders moderates the relationship between
transformational leadership and safety participation behavior.
THE MODERATING ROLE OF EMPOWERING LEADERSHIP
According to Amundsen and Martinsen (2014, 2015), empowering leadership
encompasses five different empowering leader behaviors: leading by example,
participative decision making, informing, coaching and showing concern. Leading by
example encompasses leader commitment to his / her own work as well as to the work of
their followers. Additionally, participative decision-making manifests in leaders who
genuinely explore and recognize vital input and suggestions arising from their followers.
Leader informing behaviors enables followers to be fully aware of the state of affairs at
the workplace and organizational working environment. This is critical since leaders who
consistently inform their followers about safety initiatives and programs lead to superior
safety records (Cohen, 1977). Leaders who coach their subordinates enhance the physical
communication and the dyadic interactions between leader and followers, whereas
showing concern for followers relates to the time spent by leaders deliberating on
followers’ problems. Empowering leadership positively affects employees’ job
satisfaction, commitment, and performance (Amundsen & Martinsen, 2014, 2015).
While transformational leaders encourage their followers to engage in safety
behavior, it is plausible that on its own, transformational leadership may not be adequate
to enhance employees’ safety behaviour. Therefore, it is plausible that empowering their
subordinates on matters relating to safety would augment the positive role played by
transformational leaders, consequently influencing their followers to achieve high
performance expectations. As such, empowering leadership acts as an enhancer of the
positive relationship between transformational leadership and employees’ safety
behaviour. We envisage a situation where followers who feel empowered in relation to
safety initiatives and programs at the workplace will be more likely to perceive effective
leadership as having more influence on safety behaviours. Specifically, we propose that
empowering leadership will positively enhance the impact of transformational leadership
on employees’ safety behaviours, and that empowered followers’ will be more likely to
engage in safety behaviours. In our proposed model described in Figure 1, we envisage

263
an indirect relationship between transformational leadership and safety behaviours which
is moderated by empowering leadership. Hence,
Proposition 3a: Empowering leadership moderates the relationship between
transformational leadership and safety compliance behavior.
Proposition 3b: Empowering leadership moderates the relationship between
transformational leadership and safety participation behavior.
DISCUSSIONS
This systematic literature review examined a variety of the extant studies and culminated
in a conceptual framework elucidating the relationship between transformational
leadership, empowering leadership, employees’ trust in leadership, and workplace safety
behaviors. The framework provides impetus for a behavior-oriented approach to
workplace safety research in order to generate actionable knowledge to manage accidents
and injuries in the workplace. Notably, the framework can be utilized by organizations
when executing organizational design interventions (Clarke, 2013; von Thiele Schwarz et
al., 2016; Willis et al., 2017) so as to engender and shape organizational climate and
culture of trust (Sheehan et al., 2016). In addition, the framework elicits credible research
questions which should hopefully attract more researchers trying to unpack how various
leadership styles and organizational context variables affect employees’ safety behavior
(Aryee & Hsiung, 2016; Jiang & Probost, 2016; Mullen et al., 2017; Nielsen et al., 2017;
Willis et al., 2017).
To advance organizational and safety theory regarding leadership and safety
behaviors, we propose several opportunities. First, future research should determine
which factors employees might rely on to develop trust in their workplace leader. Second,
researchers can examine the extent to which leadership empowerment behavior may
determine the impact of the four dimensions of transformational leadership. Third, there
is a need for future research to include interpersonal concepts such as leader-member
exchange as a mediator in future research model to help unpack psychological processes
through which effective leadership influences safety behavior. Finally, and in order to
enhance the generalizability of the proposed research model, we encourage more research
on leadership and safety from developing countries, specifically examining the impact of
national culture on leadership (Hofstede, 2001), and the role of the leader’s gender in the
leadership-safety research model (Eagley et al., 1995).
