CHAPTER ONE

INTRODUCTION

1.1 Background to the Study

Internal communication is widely regarded as the connective process that allows an organisation's various parts to function as a coherent whole. Katz and Kahn's (1966) open systems theory of organisations frames this idea theoretically, viewing organisations as open systems that depend on the continuous flow of information, both between their internal subsystems and with their external environment, to coordinate activity, adapt to change and sustain effective role performance among employees. Within this view, internal communication is not a peripheral administrative function but a core mechanism through which management and staff remain aligned toward organisational goals.

Nigerian empirical evidence lends practical support to this theoretical position. Maiwada and Oshionebo (2024), examining internal communication and employee relations management in the Nigeria Customs Service, found that the relationship between internal communication and employee motivation is increasingly acknowledged within Nigerian public organisations, and drew explicitly on systems theory to argue that an organisation performs best when there is full awareness of, and interaction with, its environment. Within the petroleum sector specifically, Osita-Njoku, Anyaoha and Kamalu (2020) found that internal corporate social responsibility initiatives, including healthcare provision and staff training, significantly reduced absenteeism and improved staff effectiveness at the then Nigerian National Petroleum Corporation, while Ibrahim, Ismaila and Ademuwagun examined performance management in the same organisation and found that objective setting, feedback and performance measurement significantly influenced employee engagement.

The organisational context for this study has itself changed considerably in recent years. On 1 July 2022, in line with the Petroleum Industry Act 2021, the former Nigerian National Petroleum Corporation was incorporated as Nigerian National Petroleum Company Limited (NNPC Ltd), a commercially oriented limited liability company wholly owned by the Nigerian state, intended to operate along the lines of a private international oil company. The company saw a further change in leadership in April 2025, when Bashir Bayo Ojulari became Group Chief Executive Officer, succeeding Mele Kyari, who had led the organisation since 2019. In a New Year message to staff in January 2026, Ojulari reflected on the organisation's recent performance, referenced the recruitment of new staff and a much-improved compensation package, and reaffirmed the company's strategic direction, illustrating that internal, staff-directed communication continues to be an active management concern as NNPC Ltd consolidates its post-incorporation transformation.

Given the scale of organisational change NNPC Ltd has undergone, from corporate restructuring to a change in executive leadership, understanding how internal communication relates to employee performance within the company is both timely and important. This is the concern that motivates the present study.

1.2 Statement of the Problem

Since its incorporation as a limited liability company in 2022 and its change of leadership in 2025, NNPC Ltd has undergone considerable internal transformation, including new senior management appointments, workforce expansion and revised compensation frameworks. Such changes place a premium on effective internal communication to keep a large, geographically dispersed workforce informed, aligned and motivated. However, large state-owned enterprises in Nigeria, including the petroleum sector, have historically faced criticism over bureaucratic bottlenecks and communication gaps between management and staff, conditions that, if unaddressed, could undermine employee performance regardless of management's stated commitment to transformation.

A further difficulty is that existing empirical research specific to NNPC has tended to examine related but distinct organisational practices, such as internal corporate social responsibility (Osita-Njoku et al., 2020) and performance management (Ibrahim et al.), rather than internal communication itself, while Nigerian evidence directly linking internal communication to employee performance has been drawn from other public organisations, such as the Nigeria Customs Service (Maiwada & Oshionebo, 2024), rather than from NNPC Ltd. Consequently, it remains unclear which specific dimensions of internal communication, such as downward communication from management, upward feedback channels, horizontal communication across departments, or the communication channels and technologies used, most strongly influence employee performance within NNPC Ltd's transformed corporate structure. It is this gap that the present study seeks to address.

1.3 Objectives of the Study

The broad objective of this study is to examine the relationship between internal communication and employee performance at NNPC Ltd. The specific objectives are to:

1. examine the effect of downward communication on employee performance at NNPC Ltd;

2. determine the effect of upward communication on employee performance at NNPC Ltd;

3. assess the effect of horizontal communication on employee performance at NNPC Ltd; and

4. evaluate the effect of communication channels and technology on employee performance at NNPC Ltd.

1.4 Research Questions

The study is guided by the following research questions:

1. What effect does downward communication have on employee performance at NNPC Ltd?

2. What effect does upward communication have on employee performance at NNPC Ltd?

3. What effect does horizontal communication have on employee performance at NNPC Ltd?

4. What effect do communication channels and technology have on employee performance at NNPC Ltd?

1.5 Research Hypotheses

The following null hypotheses are formulated to guide the study:

Ho1: Downward communication has no significant effect on employee performance at NNPC Ltd.

Ho2: Upward communication has no significant effect on employee performance at NNPC Ltd.

Ho3: Horizontal communication has no significant effect on employee performance at NNPC Ltd.

Ho4: Communication channels and technology have no significant effect on employee performance at NNPC Ltd.

1.6 Significance of the Study

Theoretically, the study extends Katz and Kahn's (1966) open systems theory to a newly incorporated national oil company undergoing active organisational transformation, complementing NNPC-specific evidence on internal corporate social responsibility (Osita-Njoku et al., 2020) and performance management (Ibrahim et al.) with a focused examination of internal communication itself, and drawing on parallel Nigerian public-sector evidence (Maiwada & Oshionebo, 2024).

Practically, the findings will assist the management and corporate communications function of NNPC Ltd in identifying which internal communication practices most strongly influence employee performance, thereby guiding improvements to communication policy and channels. Other Nigerian state-owned enterprises undergoing commercialisation, policymakers overseeing the implementation of the Petroleum Industry Act, and human resource practitioners in the broader oil and gas sector may also draw on the findings. The study will further serve as a reference for future researchers examining internal communication and employee performance in Nigeria's petroleum industry.

1.7 Scope of the Study

This study is delimited in content to internal communication, measured through downward communication, upward communication, horizontal communication, and communication channels and technology, and employee performance, measured from the perspective of staff of the case study organisation. Geographically, the study is confined to employees of NNPC Ltd at its corporate headquarters in Abuja. The study is further limited to a defined recent period following the company's 2025 leadership transition, during which primary data will be collected through the administration of structured questionnaires, and does not extend to a comparative assessment of NNPC Ltd's subsidiaries or joint venture partners.

1.8 Definition of Terms

Internal Communication: the exchange of information, instructions and feedback that takes place among employees and between management and staff within an organisation.

Employee Performance: the extent to which an employee carries out their job responsibilities and achieves expected outcomes within their role.

Downward Communication: the flow of information, instructions and directives from management to employees at lower levels of the organisation.

Upward Communication: the flow of feedback, suggestions and concerns from employees to management within an organisation.

Horizontal Communication: the exchange of information between employees or departments operating at the same organisational level.

Communication Channel: the medium, whether formal meetings, memos, digital platforms or other tools, through which information is transmitted within an organisation.

Open Systems Theory: a theoretical perspective viewing organisations as systems that depend on continuous information exchange, both internally and with their environment, to function and adapt effectively (Katz & Kahn, 1966).

State-Owned Enterprise: a commercial entity that is wholly or majority owned by a national government but that may operate under a corporate or limited liability structure.
