wiser, more tolerant, and open to another’s opinion or 
view thus facilitates stress management at work. 
Inadequate interaction and communication in 
working milieu such as poor communication between 
associate nurse and his head nurse, fellow nurse, other 
health professionals, or employees from another 
hospital may turn into a stressor. Poor communication 
often results in misunderstanding or misperception on 
information that may lead to error in providing 
nursing care and provoke stress. The distinction in 
human personality causes friction and conflict in the 
organization and results in work stress. However, the 
hospital has organized attempts to refresh and 
maintain interaction or relation among employees by 
organizing staf / family gathering  twice a year, 
however, no other activities implemented such as 
exercise in hospital to maintain physical and mental 
well-being. 
146 out of 231 participants with moderate 
workload were affected by mild stress (63.2%) and all 
12 participants with higher workload were also 
affected by mild stress (100%). The statistical 
analysis revealed p value 0.009 < 0.05 suggesting that 
there was a significant correlation between workload 
and work stress in nurses working in Inpatient 
Department in Building A of Dr. Cipto 
Mangunkusumo hospital. It was also revealed OR 
value of 6.791 implying that participants with 
moderate workload were 6,791 times more likely to 
be affected by stress than those with higher workload.  
This result was supported by Khoddin’s study 
(2012) which reported a significant association 
between workload and stress-related work in nurses 
with Chi Square test revealing p value 0,010. Higher 
workload brings impact on employee’s physic and 
mental and may become a stressor at work.  
A study conducted by Dewi (2014) on nurses in 
Pasar Rebo hospital reported that participants with 
higher workload were affected by severe work-
related stress (46.7%). Furthermore, the study also 
revealed that nurses with lower workload were also 
affected by severe work-related stress (44.4%). Mild 
work-related stress affected 53.3% nurses with higher 
workload and 56% nurses with lower workload.  
This finding is supported by Aoki’s study (2010) 
in Ratchaburi Thailand which concluded a significant 
link between workload and work stress among nurses. 
His study also reported that higher workload may 
increase the risk for stress among nurses. The study 
also mentioned that 70% nurses perceived high 
workload and 30% of them perceived moderate 
workload, while 70% of them were affected by 
moderate work stress and 30% of them were affected 
by severe work stress.  
Irwandi (2007) defined workload as frequency of 
activity based on mean of each activity in certain time 
interval and consists of physical or mental workload 
that may lead to work-related disorder or disease.  
Authors presumed the correlation between 
workload and work stress in nurses working in 
Inpatient Department in Building A of Dr. Cipto 
Mangunkusumo hospital stemmed from moderate or 
severe physical workload which affected them in a 
way or may even result in work-related disorder or 
disease.  All mental activities involve interpretation, 
perception, and processing of acquired information. 
At work, nurse meets and interacts with patient, 
family, visitor, fellow nurse, and other health 
professionals from multidisciplinary team and also 
complies with policies in working environment. It 
may result in excessive workload that overwhelms his 
physical, emotional, and psychological condition.  
Adiprana (2008) outlined 3 aspects in calculating 
workload which includes physical, mental, and time. 
Physical workload emphasizes on activity that 
requires physics such as bed making, lifting patient, 
pushing medical instruments, and imbalance patient-
nurse ratio. Mental workload focuses on role conflict, 
poor relationship with supervisor or colleague, and 
facing patient’s family in panic. Time workload 
includes pressure to complete nursing care 
documentation on time, pressure to make a decision 
promptly, and working overtime due to inadequate 
number of nurse. 
Individual who experiences mental burden such 
as role conflict, poor relation with supervisor or 
coworker and responsibility for patient’s recovery 
would be affected by stress at work. In addition, job 
demand that seldom exceeds employee’s capacity or, 
in other word, excessive workload that is difficult to 
deal with would provoke stress in such employee. 
Work-related stress can also be caused by amount of 
patient that surpasses amount of nurses thus require 
nurses to work overtime.  
It is safe to conclude that nurse who is assigned 
with a workload that exceeds his own capacity would 
experience burnout which affect his mental and result 
in fatigue, mood change, boredom, irritability, and 
distress. A high job demand, pressure to improve 
performance from both patient and supervisor, 
conflict with coworker or supervisor or another health 
profession, shift work, exposure to dying patient, 
number of patients overwhelming number of nurses, 
and requirement to fill out non-nursing 
documentation (such as filling out incidence report 
for monthly performance evaluation) may become a 
burden leading to work-related stress.
