However, 5 respondents feel that no leave facilities should be increased.
All employees said that extra facilities like, mobile phone, ID card and Business card play vital role in employee satisfaction. Reasons they provide are that they give identity and recognition make the employee a part of the organization and also work as motivational factors.
8 out of 30 employees feel that the premises should have proper fire exit. 2 of the employees want the area to be more hygienic. 8 employees that are the maximum employees want the organization to be stricter about the entrance of outside people. 4 of them demand for logistic and safety training.3 employees feel that the area should have CC camera.

For more details of the qualitative data please look at the Appendix.
ANALYSIS OF THE COLLECTED DATA
All data collected is analyzed in details in this part. All the diagrams included in this part are derived from SPSS. Some diagrams and tables are provided later in the Appendix. Tables provided in the Part 4.1 are also used in the analysis.
In the survey the maximum respondents were male. The respondents are mostly between the age of 20-30. Moreover, maximum respondents are Specialist. In addition, the maximum work experience respondents have is 8 years, in which the highest number of employees has the work experience of 3 years.
Leaves
From the Table 4 (A) an overall picture of the level of employee satisfaction regarding leave can be seen. Digits marked in Red are the total counts of responses, which show that the employees are satisfied with the rules and regulations and duration of all leaves. However, a good amount of employees are somewhat satisfied with the leaves. Fortunately a very few number of employees are dissatisfied with the aspects of leaves.Incase of Annual leave the maximum employees are happy with the rules and durations. However, a wealthy amount of employees are somewhat satisfied, but no one seems to be dissatisfied with the leave.
Most employees seem to be perfectly satisfied with Medical leave. In fact the highest amount of employees responded positively in case of this leave. However one employee seems to be somewhat dissatisfied.
In case of leave without pay and compensatory day-off most of the employees are neutral. The reason behind this is that some of them did not experience these leaves and some of them did not know that the company is offering these leaves.
In case of Maternity leave most female employees are somewhat satisfied, but a very few were dissatisfied because the organization has not yet implemented the maternity leave of 6 months as declared by the Government. But it has been heard that very soon the company will offer maternity leave for duration as declared by the Government (this information is highlighted in the qualitative part of the questionnaire).
The result of paternity leave was very much fluctuating. Most male employees were somewhat satisfactory and neutral. In the quantitative question as mentioned earlier most men said that the paternity leave should be extended so that they can fulfill their responsibility while the baby birth.
Salary And Benefits
The result regarding salary and benefit is quite like the result in case of leave. From the Table 4 (B) it can be seen that maximum employees are somewhat satisfied with the rules and regulations of their salary and benefits.
As shown in the table in case of allowance most of the employees are satisfied. Moreover, a healthy amount of employees are somewhat satisfied with the allowance that the company provides. Very few employees expressed their dissatisfaction regarding salary and benefits.
Again in case of Festival bonus the result is similar to the result of allowances. Most employees are somewhat satisfied, as they get the amount equal to their basic salary during Eid and Christmas.
Overtime allowance is given only to some Grades of employees as mentioned earlier. According to the table maximum numbers of employees are somewhat satisfied. A few amounts are satisfied, but more than that employees are neutral about the case.
In case of shifts the highest amount of employees are neutral as they are not use to this benefit. Most of the employees have not done the shift duty. Compared to other benefits a very few employees are satisfied and some what satisfied with the benefit. Some of the employees who have done the duty are dissatisfied; they feel that the amount provided is not sufficient.
In case of holiday allowance most of the employees are somewhat satisfied and few of them are satisfied. On the other hand most of the employees are neutral. This is because they have not experienced the benefit of holiday allowance. However, a very few employees are dissatisfied with the facilities provided in the holiday allowance.
The salary review is done so that the amount of salary is set in such way that it gives complete support to the lifestyle of employees. Most of the employees are somewhat satisfied with the facility. Moreover, some are neutral about the facility as they do not have idea about the method of salary review. However, some are dissatisfied as they feel that the organization do not go through this facility accordingly.
Maximum employees are neutral in this case. This may be because their work experience is less than 5 years, as an employee is only eligible to contribute to Provident fund and gratuity after 5 years of membership of the fund. Moreover, a good amount of employees are somewhat satisfied with the facility. Fortunately a very few amount is somewhat dissatisfied with the facility.
Most of the employees are neutral about the traveling and accommodation, as they neither found it impressive nor unbeneficial. A good amount of employees are somewhat satisfied as they find it very motivating to get facilitated during travel.
Most of the employees are satisfied with the timeliness of salary handover, as they feel that they get their monthly salary on time. Then a good amount of employees are somewhat satisfied as they feel sometimes it becomes late in receiving the salary. However, very few of them are neutral and only one employee is dissatisfied.
Motivation
Before deriving the level of satisfaction regarding the motivational factors, it was very essential to find out how much important are these motivational factors to the employees. In Table 4 (C) it is shown that most or almost every employee find performance bonus and reward and recognition very important.
In Table 4 (D) it is shown that most of the employees are somewhat satisfied with the performance bonus and reward and recognition provided by the company. The employees feel that the company provides bonus based on both individual and group performance. Moreover, they are happy with the rewards and recognition provided by the company. However a very few amount of employees are dissatisfied which can have a negative impact on the company and employee productivity. Some are neutral as they are neither satisfied nor dissatisfied with the motivational factor provided by the company.
Moreover, respondents were asked whether ID card, Business cards and mobile phone play a vital role in employee satisfaction or not. Every one said that these work as a motivational factor, as it gives recognition and mobile phone work as a motivation for employees.
Safety And Security
Most of the employees are satisfied and somewhat satisfied with the facilities provided for the safety and security in the organization. A very few seems to be dissatisfied the reason behind this was found when the employees were asked to specify their requirements for safety and security.
Almost all employees stated that more facilities for safety and security are required. Maximum employees said that there should be more restrictions to outsiders and the fire exit should be improved. However, one of the employees stated a very essential monitory reason, which is the employee feels that festival bonus should be included in contractual sector as well.
Discipline
Disciplinary acts followed by Robi are mention earlier in the report. Most of the employees that are 56.7% find the disciplinary act and rules of punishment averagely fair. Moreover 43.3% find it fair. 60% of the employees stated that the organization is improving due to these disciplinary acts and punishments. However, some of them are neutral as they not sure whether it is having an impact on the organization or not. Therefore most of the employees were neutral when they were asked whether the organization follows these acts accordingly or not.
Assessment (Evaluation of Employees)
At the end of every year mostly in December an employee assessment is done to measure the level of performance of the employees. Most of the employees seem to be satisfied with the employee assessment, as 36.7% said that the assessment is fair and 60% of them said that the environment of the organization is improving due to the assessment, as all employees are striving to perform better every year to have a better evaluation result.
As one of the employees in the organization said that the organization has made some changes in the assessment process five times in last five years. I could not know about the changes as it was confidential, but I wanted to find out whether these changes have positive impact on the organization. 70% of the respondents stated that the organization is positively affected by these changes.
Level Of Satisfaction Of The Entire Environment In Robi
As the dependent variable of the research is Employee Satisfaction it was very essential to know the level of employee satisfaction regarding the entire environment of Robi. 70% of the employees are satisfied with the environment of Robi. However, this information is not enough to draw conclusion therefore further analysis of data in conducted.
Factor That Link Mostly To Employee satisfaction
It is not enough to know the level of employee satisfaction therefore the respondents were asked to state that on which factor does the employee’s level of satisfaction is mostly based. The maximum number of employees that is 73.3% said that salary and benefit boosts up the level of employee satisfaction.
CORRELATIONS
It is mentioned earlier that the Dependant variable is Employee satisfaction. The variable is correlated with independent variables like gender, age, designation, and work experience at Robi to measure the level of employee satisfaction in the view of these aspects individually. Figures and tables are derived with the help of SPSS by the process of Cross Tabulation

The purpose of doing this correlation between the levels of employee is satisfaction and gender is to project that which gender is more satisfied in the organization. As shown in Table 4 (E) 12 out of 19 male respondents are satisfied, where as 9 out of 11 female employees are satisfied with the entire environment of Robi Axiata Limited. 1 male employee is dissatisfied, where none of the female employees are completely dissatisfied. Therefore, the female employees are more satisfied than male employees at Robi. In the Figure 3 the bar of male employees are higher as there were not male respondents in the survey.

Therefore, it can be stated that Engineers and Managers are mostly satisfied in the Technology Division of Robi. However, in the Figure 5 the bar of Specialist is highest because most of the respondents
were specialist.

Years of Experience at the Organization
In the Table 4(H) and the Figure 6 it is shown that employees with the work experience of 1 year, 5 years, 8 years, less than 1 year, more than 1 year, more than 5 years and more than 6 years are completely satisfied with the environment of the company. However, Employees with the work experience of 2-7 years and more than 3 years to less than 5 years have slight dissatisfaction with the environment. The reason behind this is that new employees are eager to perform better and old employees are more committed to the organization. It is normally in between the period of continuous service when the employee’s satisfaction level deteriorates. This is the period when they try to switch jobs and search for other options. Moreover as you can see in the diagram it is during 5 years time the satisfaction starts rising, this can also be due to rewards and recognition. I have mentioned earlier that Robi gives gold medals for continuous service of 5 years. Therefore employees are overwhelmed due to the reward and their satisfaction level rises.

In the Table 4 (I) and Figure 7 it is shown that most satisfied employees finds salary and benefits as the most important factor that effect the level of employee satisfaction. The second most important factor is motivation. However, leaves and assessment are not that effective factor. Therefore, it is clear that Robi should work more on Salary and Benefits in order to keep their employees satisfied.

Female employees are most satisfied than male employees. This may be because males are mostly the earning member of the family, so their expectation is higher than that of female.
New employees and old employees are more satisfied as they are more commited to their work.
Salary and benefits and motivational factors play avital role in satisfying employees.
Employees at Robi are eagered to have some training ragarding safety and security.
Most male employees feels that paternity leave has to be extended.
According to some employees Casual leave should be introduced at Robi.
Most employees are very neutral about the Disciplinary act and Punishments of the organization.
Changes in the employee assessment system have a positive impact on Robi.
Employees satisfactory level at Robi Axiata Limited seems to be considerable. However, the company needs to work a lot to retain their old employees or sustain the existing good performers.
