METAL ENDÜSTRİSİNDE ÇEVRESEL KOŞULLARIN İŞ PERFORMANSINA ETKİLERİ

Çevre faktörleri (gürültü, sıcaklık, nem, aydınlatma vb.), işyerlerinde çalışan işçiler üzerine, iş performansı, verimlilik, iş sağlığı ve güvenlik açısından dolaylı veya direkt etki ederler. Uygun olmayan koşullar, çalışanın görevlere karşı konsantrasyonunu azaltmakta, bu da düşük performans, yüksek ürün firesi, iş kazalarına neden olmaktadır. Hangi faktörlerin iş performansını geliştirme ve kazalardan kaçınmada nasıl etkiye sahip olduğunu değerlendirmek önemlidir. Bu çalışmada amaç, çevre  faktörlerinin iş performans üzerine etkilerini araştırmaktır. Metal endüstrisinde faaliyet gösteren 8 işletmede 92 işyeri ve işçiden veriler toplanmıştır. Dört çevre faktörünü içeren 2760 ölçümün ortalama değerleri; gürültü 91,88 dB(A), sıcaklık 23,99°C, nem %36,35 ve aydınlatma şiddeti 289,34 lüks olarak belirlenmiştir. 15 davranışsal performans kriterini içeren iş performansı 3.30/5.0 bulunmuştur. Tüm işçiler için eniyi performans “Amirlerine saygı” kriterindedir. Sonuçlar, gürültü ile “Verimli çalışma”, sıcaklık ve aydınlatma ile “Titiz ve düzenli çalışma”, nem ile “Kalite” arasında anlamlı etki olduğunu göstermektedir.

THE EFFECTS OF ENVIRONMENTAL FACTORS ON JOB PERFORMANCE IN METAL INDUSTRY

Environmental factors such as noise, temperature, humidity and illumination have direct or indirect effects on worker’s job performance, productivity, occupational health and safety. Inappropriate conditions may decrease worker’s concentration towards tasks which lead to low performance, poor quality, workplace hazards. It is important to assess which factor has effect to improve job performance and avoid accidents. The objective of this cross-sectional research is to investigate the effects of environmental factors on job performance. Data are gathered from 92 workplaces and blue-collar workers in eight manufacturing companies in metal industry. The average levels of 2760 measurements including four environmental factors are determined as 91.88 dB(A) for noise, 23.99 °C for temperature, 36.35% for humidity and 289.34 lx for illumination. The overall job performance score consisted of 15 contextual performance criteria is found as 3.30 of 5.00. The best performance for all the workers is identified as “Treatment the supervisor with respect” criterion. The results highlight the significant effect of noise on “productivity”, temperature and illumination on “working systematically” and humidity on “quality”.
