  Abstract 

Introduction: Increasing demands, exacting management, poor ergonomics, and intense competition within and without are likely to contribute to stress among the railway engine pilots. This excess of stress and its consequences cost very high to both the organization and the consumers. Aims and Objectives: This study aims to identify the particular stressors affecting the railway engine pilots and their level of occupational stress in order to improve the safety, efficiency, and overall productivity of the railways and to propose the remedies. Materials and Methods: A cross-sectional study conducted at Central Hospital, SECR, Bilaspur, from 20/09/10 to 20/11/10, involving a study sample of 100 healthy Loco Pilots and 100 controls with similar safety category meeting the set inclusion and exclusion criteria, subjected to cross-sectional interviews and questionnaires. Results: Job stress correlated significantly with fatigue (P<0.001), ergonomics of work place (P<0.05) (particularly the postural discomfort and cab space), management pressure (P<0.01), high job demand (P<0.001), low control and low support at work (P<0.01), biological functions (P<0.05), and absenteeism (P<0.001). Top ten stressors have been identified and postural discomfort tops the list. The study also identifies minimal efforts from administration to reduce stress of its employees. Conclusion: The high demand, low control, and low support at the work with difficult work environment and inadequate recreation at the place of intermediary rest corroborates with development of stress affecting the normal biological functions leading to either avoidance of duty or making the railway engine pilots susceptible to fatigue and drowsiness, neglect, injuries, and accidents.

  Introduction Top


Occupational stress is the particular relationship between the person and the environment, appraised by the individual as taxing, exceeding his/her resources or sources, and endangering his/her wellbeing. It is not only the characteristics of the environmental factors, but also the perception of the person about the demands of the environment, his/her coping resources, his/her sources, and type of social support.

The area where the study has been carried out is known for its heavy passenger and freight traffic and is the source of highest income over Indian Railways.


  Background Top


This project concerns the problems which touch the railway sector globally. The actual evolutionary processes (swift changes in the field of technology, customers' demand, management, increasing economical requirements, pressure of the public opinion, growing competition, etc) contributing to the development of stable and recurrent stress of the train drivers who have the responsibility of carrying thousands of life to their destinations. This excess of stress and its consequences cost very high to the organization.

The study has been carried out on the background of increasing work load and management push due to growing competition, increasing traffic and increasing pressure of opinion from the media and public with obvious reason for development of stress.


  Aims and Objectives Top


  1. To identify job-related stressors in the Railways in relation to the work environment of Railway Engine Pilots as well as to assess level of stress among them.
  2. To identify one to one relationship of occupational stress with absenteeism, fatigue, symptoms of stress, familial discord, and biological functions.
  3. Help Railways detect, analyse, anticipate, and modify the influencing factors.


Place of study : Central Hospital, South East Central Railway, BILASPUR


  Materials and Methods Top


Sample Selection and Sample size

The study sample consisted of 100 healthy train drivers and 100 controls who have similar safety category but sedentary job attending the periodical medical examination on Tuesdays and Fridays with no illness as per the ICD-10 criteria, referred from the department during the period between 20/09/10 and 20/11/10.

Inclusion criteria

  1. Subjects up to 50 years of age with no clinical diagnosis as per ICD-10 diagnostic criteria, referred from the department during the period between 20/09/10 and 30/10/10 were included in the study.
  2. Subjects included were not on any medicines.
  3. Subjects coming for PME on Tuesday and Friday were only included in the study.
  4. Subjects consenting to participate were included in the study.
  5. Subjects of SEC Railway, Bilaspur division were only included in the study.


Exclusion Criteria

  1. Subjects with any evidence of organic basis of any pathology through history, clinical examination, or laboratory reports were excluded from the study.
  2. Subjects with significant physical illness and above 50 years were excluded from the study.
  3. Subjects with any psychiatric disorder as per assessment scale - Brief psychiatric rating scale (BPRS) - were excluded from the study.
  4. Subjects not giving consent to participate in the study were excluded from the study.


Subjects attending PME on days other than Tuesday and Friday were excluded from the study. Subjects consisted of Railway Pilots concerned with controlling of train and control consisted of station managers and station superintendents. Both the subjects and controls in the study were safety category staff requiring similar mental agility and decision-making skills sharing the same set of traffic information though the latter control multiple traffic information at a time. Subjects and controls satisfying the inclusion and exclusion criteria were included in the study and were subjected to live interview lasting about 20 min with specially designed questionnaire, Job Stress Rating Scale (JSRS) and Physical effect of stress (PESS) scale, and Brief Psychiatric rating scale (BPRS). Inter-rater and intra-rater reliability were good.

Diagnostic Tools used were:

  1. Specially designed clinical performa/questionnaire.
  2. PESS for assessment of physical symptom of job stress. [1]
  3. JSRS to assess the level of stress. [2]
  4. BPRS to exclude psychiatric reasons for proneness to stress. [3]
  5. Stress Reducers Rating Scale (SRRS) for rating the management regarding what is done by the management to reduce stress of its employees.


BPRS is a clinical interview for assessment of psychiatric symptom and severity. It contains 18 items and rating is done on 7-point severity scale (from 0 to 6).

JSRS consists of 12 items and is divided into three subscales, i.e. demand, control, and support. It is 1-point rating scale with a maximum score of 12.

PESS consists of 14 items and has three subscales, i.e. physical symptoms pertaining to immune system, nutrition, and physical activities. It is 4-point rating scale with a maximum score of 42.

SRRS consists of 20 items. It is rating scale with 5 points for each yes answer with maximum score of 100. Sr. DEE (OP)/SECR/BSP, Sr. DME/SECR/BSP, and Sr. DOM/SECR/BSP were interviewed on behalf of the management for rating the SRSS.

Statistics

Data generated in this study were subjected to analysis using computerized SPSS version so as to identify any significant stressor and one to one correlation with factors like absenteeism, fatigue, psychological and physical problems, marital or familial discord and biological functions.

  Discussion Top


The study reveals that Railway Pilots have high level of job stress as compared to control who have mild level of job stress. [6]

The questionnaire designed consisted of 11 heads with average 6 questions under each head. Significant stressors have been found, among the subsets of:- (a) Ergonomic of the Cab, (b) Environmental Stressor, (c) Management pressure. Among the group of Ergonomic of Cab, the most stressing were postural discomfort, non-spaciousness, and lack of toilet in the workplace. Among the group of Environmental Stressor, the most stressing factors were noisiness, improper protection from extremes of temperature, and rain, whereas among the group of Management Pressure as stressor, the most stressing were long duty and improper rest, unhappiness with place of intermediary rest, and consequences of making mistakes severe with fear of losing job. [7]

Job stress has been found to strongly correlate with high job demands, low control over the work, and low support at work. [8]

Among the top ten stressors identified, the top three were postural discomfort and lack of adequate space, noisy workplace, and long duties and improper rest.

The most common symptoms of stress identified include disrupted sexual functions, muscle ache and pains, sleep disturbances, headache, stomach problems, irritability and anger, and frustration and anxiety.

Job stress has been found to significantly correlate with stressors like vibration, disrupted sexual behavior, cab discomfort, long duties improper rest frequent absenteeism, noise, sleep disturbances, irregular food habits, and fatigue similar to that of Prahastuti et al. [9],[10]

Significant negative correlation has been found with familial discord and absenteeism.

Disrupted sexual functions have been identified resulting due to long duties and improper rest and inability to meet with household demands leading to familial discord.

The study has identified that working with discomfort and fatigue without proper sitting facility, make the pilots in-alert, inattentive more drowsy, and susceptible to falling asleep: safety at stake.

It is also identified that working in a recently introduced comfortable AC cabs (ongoing pilot project) doesn't cause fatigue even after long hours of duty rather it keeps them fresh and are able to keep alert, attentive, and least likely to get drowsy: resultant: more safe working.

Recommendations

In many railways today, there are fewer people doing the same amount of work due to increased number of trains and trips owing to increased loading targets. The implications of which is managing the work by the same group of employees who often have increased stress, out of fear of layoffs due to being overworked.

Solution : To combat the increased work load and take care of mental and physical health of the railway pilots, the cadre strength of the railway pilots concerned with safety of thousands of lives needs to be increased adequately so as to take care of long duty and improper rest, disrupted sexual habits, and safety at large.

Ergonomics of the Cab with respect to discomfort due to insufficient cab space, seat discomfort, environmental stressors, and absence of toilet in job of long duties and safety of thousands of life, has been identified as most stressing in this study.

Solution : As these factors are beyond own control, the employee needs to be thought ways to combat and ventilate stress. [11] Management on the other hand should take steps to improve work condition - like designing of cabs to be comfortable, spacious with proper seats, air-conditioned to protect from environmental stressors, and with facility of a toilet within the cab.

The goal of stress psychotherapy is to remind employees that they should keep their focus on things they can control as well as for the employer to recognize, appreciate, and reward employees for good work and extraordinary efforts. [12]

Solution : Management seriously needs to have periodical counselling sessions and programmes to teach relaxation and de-stressing. It is recommended that a clinical psychologist be recruited at all Zonal and Divisional hospitals of Railways for the purpose.

Stress can manifest itself in a decline in performance of an employee which may trigger an employer's discipline policy. It can aggravate existing health problems or create behavioural health issues. Sick time and leave issues may prop up.

Solution : Stress management and self-care training should be designed to help employees manage work versus life balance and understand how stress can affect family members, friends, co-workers, and self. [13]

The study has identified lack of recreational activities at the place of intermediary rest and that administration expects arrangement for sleeping and meditation enough for de-stressing of employees.

Solution : During the course of data collection and interaction with the subjects, it has been found that recreation is perceived as best de-stressor by both subjects and control and the following was desired by the employees under study: "a recreation room with TVs, Magazines, carom boards, and Table tennis boards" - same is recommended.

What is being done by railways?

Problem has been identified by the Railways and recruitment process is in progress. 500 new recruits added in year 2010 and 600 new recruitment to be done in 2011. Still not enough as traffic and target has increased 5-folds in past 20 years and concerned employees have been added to 3.5-folds only.

As a pilot project by the Indian Railways, five to six new engines have been introduced in almost all divisions which are spacious, with comfortable seats, and air conditioned. But most of the divisions have removed the ACs and replaced it with coolers - may be due to problem faced in exchange of signals. Need for a toilet within the cab is identified but no solution has been found yet. Worth mentionable is electronic signal exchange as used in most railways especially in Europe in high speed trains could be tried where the both sides of engine have couple of lights one each under control of driver as well as his assistant so that both the lights don't fail, which are lit for signal exchange at stations.

Nothing is done for employees' de-stressing.

Employees are recognized, appreciated, and rewarded for good work done.

The place of intermediary rest is being renovated at almost every place. Has been made centrally air cooled at few places in S.E.C. Railway and is planned for at other places. News papers and meditation room is provided, but there is no recreational facilities.


  Conclusion Top


The high demand, low control over work, and low support at work with difficult work environment and inadequate recreation at the place of intermediary rest corroborates with development of stress affecting the normal biological functioning leading to either avoidance of duties or making railway pilots susceptible to fatigue and drowsiness, neglect, injuries, and accidents.

Inadequate efforts by the management to reduce the stress of its employees are evident in the study.

Urgency to have clinical psychologist is brought to fore.
