3) What are Insomnia, Emotions and Job Satisfaction?
3.1) Insomnia:
The term insomnia is derived from the latin word insomnus, which, literally translated, means “no sleep”. Insomnia usually refers to indicators such as ‘sleep quality’ and ‘sleep maintenance’. We are interested in finding out sleep problems among working population in Dutch Bangla Bank Limited. Therefore in our study, we have focused on Insomnia rather then sleep duration as our central predictors of emotions and job satisfaction during work.   
            
3.2) Emotions of Hostility, Joviality, Fatigue and Attentiveness:
Emotions are a reaction to a specific event. In the current study, we adopt the perspective that a poor night of sleep constitutes an “event” that produces a specific emotional reaction among the managers in Dutch Bangla Bank Limited. Although we use the label emotion when referring to the affective experiences that follow a poor night of sleep, in doing so, we are focusing primarily on the distinguishing feature of emotions that they are a reaction to a specific event.
  • Hostility means angry or less happy.
  • Joviality refers to feelings of happiness and enthusiasm.
  • Fatigue is representing feelings of sluggishness and tiredness.
  • Attentiveness refers to feelings of alertness and concentration.
3.3) Job Satisfaction:
Job satisfactions are multidimensional psychological responses to one’s job.     

These responses have cognitive (evaluative), affective (or emotional), and behavioral components. Job satisfactions refer to internal cognitive and affective states accessible by means of verbal—or other behavioral—and emotional responses. Thus, we view job satisfaction as a stable characteristic that varies across individuals.

4) Development of Hypotheses:
We assume some hypothesis for requirement of our study to analyze data that we have collected. To make specific decision from our data we make the following hypothesis: 

4.1) Effect of insomnia on other variables:
  • The relation between insomnia and attentiveness is negative. This means the more insomnia one has the less he will be suffering from attention disorder in his work place and vice versa.
  • The relation between insomnia and hostility is positive. This means the more insomnia one has the more he will be experiencing hostility to others in his work place and vice versa.
  • The relation between insomnia and joviality is negative. This means the more insomnia one has the less he will be experiencing joviality disorder and vice versa.
  • The relation between insomnia and fatigue is positive. This means the more insomnia one has the more he will be experiencing fatigue in his work place and vice versa.
4.2)  Relationship between workplace environment and other variables:
  • The relation between workplace environment and job satisfaction is positive.
  • The relation between workplace environment and competence is positive.
