ABSTRACT
Office ergonomics is a widely acceptable means of providing an enabling environment that best
facilitates employees’ performance and general productivity. This study sought to find out the
impact of office ergonomics on employee performance using the Ghana National Petroleum
Corporation (GNPC) as a case study. The objectives of the study were to analyze the office
design, finishes and furnishing of the head office building of GNPC, identify ergonomic features
in the design, finishes and furnishing in terms of their suitability and comfort of the employees,
assess the impact of office ergonomics on the performance of GNPC employees at the Petroleum
House in Tema and finally propose specific ergonomically based interventions that would
address employee health, comfort and wellbeing and thereby enhance optimum performance.
The study was based on a sample of 88 GNPC staff randomly drawn from various departments
and units at the Petroleum House, as well as 10 senior managers. Data for the study obtained
mainly from the administration of questionnaires was analyzed quantitatively using the SPSS and
Microsoft Excel and presented with the aid of frequency distributions, pie charts, tables, pictures
and graphs. The research identified considerable office ergonomic deficiencies which included
uninspiring and old-fashioned office design and décor (largely cellular offices), use of dark
wooden partitions resulting in poorly illuminated offices, and continuous use of un-ergonomic
furniture at the Petroleum House. The study also confirmed that the ergonomic deficiencies have
had varying adverse effects on the performance of GNPC employees by between 20-80 percent.
The study recommends the relocation of the GNPC head office to a new modern facility
designed and furnished to suit the peculiar needs of the Corporation. The development and
operation of a Real Estate Policy that leverages on the workplace environment to attract, retain
and boost employee performance has also been recommended.
