Pekerjaan, Nonpekerjaan, dan Psikologi Sosial sebagai Penyebab Kelelahan Operator Alat Berat di Industi Pertambangan Batu Bara

Kelelahan merupakan salah satu faktor penyebab kecelakaan transportasi, ditandai dengan menurunnya kinerja fisik dan mental yang mengakibatkan kurangnya kewaspadaan karena rasa kantuk. Penelitian ini bertujuan untuk mengetahui faktor risiko dan faktor pendukung kelelahan pada operator alat berat. Penelitian dilakukan pada operator alat berat di 3 tambang batubara di Kalimantan (2 area di Kalimantan Timur dan 1 area di Kalimantan Selatan), melibatkan 353 operator alat berat yang bekerja dengan 3 sif. Hasilnya menunjukkan bahwa keluhan kelelahan semakin tinggi dengan meningkatnya usia, lama kerja, dan kerja pada sif 3 (malam hari). Kelelahan paling banyak dirasakan oleh operator dump truck (bagian hauling) yang dipengaruhi oleh faktor-faktor pekerjaan (postur saat bekerja, faktor variasi pekerjaan, beban kerja dan vigilance) dan faktor-faktor bukan pekerjaan (kondisi medan atau area tambang yang berisiko, penerangan yang kurang pada malam hari, dan rute yang selalu berubah). Faktor lainnya berkaitan dengan masalah sosial-psikologis, baik yang berhubungan dengan pekerjaan maupun lingkungan kerja, seperti waktu istirahat, standar gaji yang belum memadai, pengaturan jadwal cuti yang sering tidak jelas, dan masalah karier. Disimpulkan, secara umum kelelahan meningkat dengan bertambahnya usia dan lama kerja, dengan kelelahan yang lebih besar pada pekerja sif 3. Umumnya, penurunan waktu reaksi pekerja sif malam lebih besar daripada waktu reaksi pekerja sif siang.Fatigue is one of the causes of transportation accidents, characterized by reduced physical and mental performance resulting in reduced alertness due to drowsiness. The present study was to determine the risk factors and contributing factors of fatigue suffered by heavy equipment operators. The study was conducted at three coal mining sites in Kalimantan (2 areas in East Kalimantan and 1 area in South Kalimantan) involving 353 heavy equipment operators who work in shifts. It was found that fatigue complaint is higher by older age, longer work, and work at shift 3 (night time). The fatigue is mostly complained by dump truck (hauling part) operators which was influenced by work-related factors (work posture, job variety, workload, vigilance) and non-work related factors (terrain or mine risk area, lack of lighting at night, and route track which is always changed). Another factors related with socio-psychological factors, either related with job or working environment, such as adequacy of rest time, remuneration system, leave system, and insecure career. It is concluded that in general the fatigues were increased as the worker ages were older and longer duration of work, with higher fatigues were suffered at shift 3. Generally, reduced reaction time among shift 3 workers is higher than that those of daytime shift.

Adverse social behavior (ASB) by colleagues or superiors in the workplace is considered highly stressful for workers in South Korea. The authors investigate the mechanism by which ASB reduces productivity (measured in terms of sickness presenteeism (SP)), by examining the potential mediating role of musculoskeletal disorders (MSDs). All data are derived from the fourth Korean Working Conditions Survey, which investigated a representative sample of the working population. The authors analyze their general characteristics (age, gender, income, and education), work-related factors (job type, occupational ergonomic risk, job resource, employment contract, work schedule, working hour, and job demand), and health-related factors (self-rated health and MSDs). The authors use a two-step regression analysis to estimate the direct effect of ASB on SP and the indirect effect of SP via MSDs. The authors find that MSDs mediate 16.7% of the total effect of ASB on SP. When employment type and job conditions are considered, the role of the mediating variable in the group with a permanent contract, no shift or night work, and high working time is greater than the counterpart of each variable. Various strategies are needed to address MSDs according to the working environment, which might help limit the negative impact of ASB on SP.

BACKGROUND: The percentage of drivers aged ≥65 years among all Korean taxi drivers has risen sharply from 3.2% in 2006 to 22.0% in 2016. OBJECTIVE: This study compared the characteristics of work-related traffic crashes between male taxi drivers aged ≥65 years and <65 years. METHODS: Using the national compensation data of South Korea, 586 injured male taxi drivers were analyzed based on driver-related (work experience, company size, employment status, injured body part, and injury type) and crash-related factors (time and day of the crash, weather condition, road type, violation and drowsiness) by age group. RESULTS: For the injured drivers aged ≥65, percentages of the crashes related to some factors were lower than those of the drivers aged <65 years: at night (55.2% vs. 64.0%), on rainy or snowy day (7.8% vs. 21.3%), on straight road (40.5% vs 50.9%) and on the expressway (6.9% vs. 13.0%). However, the percentage of the crashes related to a violation for the injured drivers aged ≥65 years (23.3%) was higher than that of the drivers aged <65 years (13.4%). Furthermore, the taxi drivers aged ≥65 years had a higher death rate (14.7%) than the drivers aged <65 years (8.5%). CONCLUSIONS: The results can be useful for injury prevention policies and guidelines for elderly taxi drivers such as strengthened qualification tests for the aged drivers and improvement of the working environment.

Increased Risk

The COVID-19 pandemic has introduced a number of added obstacles to safe employment for already-challenged essential workers. Essential workers not employed in the health sector generally include racially diverse, low-wage workers whose jobs require close interaction with the public and/or close proximity to their coworkers, placing them at increased risk of infection. A narrative review facilitated the analyses of health outcome data in these workers and contributing factors to illness related to limited workplace protections and a lack of organizational support. Findings suggest that this already marginalized population may also be at increased risk of “moral injury” due to specific work-related factors, such as limited personal protective equipment (PPE) and the failure of the employer, as the safety and health “duty holder,” to protect workers. Evidence suggests that ethical and, in some cases, legally required safety protections benefit not only the individual worker, but an employer’s enterprise and the larger community which can retain access to resilient, essential services.

Aims: The aim of the study was to analyze the relationship between health, lifestyle, work-related and sociodemographic factors, and older nurses' exit from the labor market to Post-Employment Wage (PEW). PEW is an early retirement scheme to make it possible for workers to retire at the age of 60. Methods: The study was based on 5,538 nurses in the age of 51—59 who in 1993 completed a questionnaire on health, lifestyle, working environment, and sociodemographic factors. The survey information was combined with longitudinal data from the Danish Integrated Database for Labor Market Research compiled by Statistics Denmark. The follow-up period was from 1993 to 2002. Results: Nurses who had poor self-rated health were more likely to join PEW compared with nurses who considered their health as good (HR 1.28, 95% CI 1.16— 1.41). Low job influence, high workload, and physical job demands only marginally increased the probability of retiring. Nurses who have relatively low gross incomes had an increased probability of entering PEW compared with nurses with relatively high gross incomes (HR 1.60, CI 1.43—1.79). Having a spouse increased the probability of joining PEW, especially having a spouse who had retired or was unemployed. Conclusions: The retirement age among nurses is influenced by a number of sociodemographic, work-related, and health-related factors. Poor health, low income, living outside the Copenhagen area, being married, having a spouse who is outside the labor force, and working in the daytime are all predictors of early retirement among nurses. Poor working environment only marginally increased the probability of retiring early.

Overall Job Satisfaction

Abstract Objective The study aims to analyze job satisfaction among registered clinical dentists in the United Arab Emirates (UAE), and also to explore satisfaction with different work environmental factors and relate them to overall job satisfaction. Materials and Methods A survey modified from the American Dental Association version of job satisfaction published in 2013 to 2014, was given to 197 licensed dentists in Dubai and Sharjah cities in the UAE. The questionnaire included four main sections, in addition to the demographic factors questions. All questions were answered using the 5-point Likert scale. The only exception was the comfortability in the working environment which was answered using a 3-point Likert scale. Statistical Analysis Categorical data were presented as frequencies and percentages, and data were analyzed using means and standard deviations. Regression analysis was performed with overall job satisfaction as the dependent variable and seven aspects of satisfaction with work and individual characteristics as the independent variables. An α level of 0.05 was used for tests of statistical significance. Results The overall job satisfaction of dentists working in the UAE is high compared with other countries. Highest satisfaction was related to the relationship with patients, colleagues, and staff. On the other hand, the least satisfaction was linked to the opportunity for part-time work and benefits package. There were no significant differences between male and female participants regarding all work-related factors apart from autonomy. However, private sector dentists had a higher level of satisfaction compared with the public sector in many work-related factors. Conclusion There are various dimensions that collectively influence the level of overall job satisfaction. Difference existing between the levels of job satisfaction among private and public sector dentists and between male and female dentists need to be addressed to increase the level of job satisfaction among UAE dentists and thus improve all dental care system.

Background: Research shows that there is a high prevalence of suicide among nurses. Despite this, it has been 15 years since the last literature review on the subject was published. Aim: The aim of this article is to review the knowledge currently available on the risk of suicide among nurses and on contributory risk factors. Method: A search was conducted in electronic databases using keywords related to prevalence and risk factors of suicide among nurses. The abstracts were analyzed by reviewers according to selection criteria. Selected articles were submitted to a full-text review and their key elements were summarized. Results: Only nine articles were eligible for inclusion in this review. The results of this literature review highlight both the troubling high prevalence of suicide among nurses as well as the persistent lack of studies that examine this issue. Conclusion: Considering that the effects of several factors related to nurses' work and work settings are associated with high stress, distress, or psychiatric problems, we highlight the relevance of investigating work-related factors associated with nurses' risk of suicide. Several avenues for future studies are discussed as well as possible research methods.
