Project in any field of study is the kind of achievement for which every student is looking for and thinking upon throughout his academic session that what it should be & how should it be completed. It is definitely a keen desire of every student to full fill his requirement. It needs through study untiring efforts, hard work with full devotion towards the cause and last but not the least proper guidance and corporation from seniors and instructors.
I extend my gratitude to “Miss Saira Majeed” whose guidance throughout the project and broadened vision by her ample experience and served as a lighthouse in this incredible venture for completion of the project.

EMPLOYEE TURNOVER
Introduction:
Employee turnover is the number of permanent employees leaving the company within the reported period versus the number of actual active permanent employees on the last day of the previous reported period.
Definition:
“The ratio of the number of worker that had to be replaced in a given time period to the average number of workers.”
Explanation:
The number of leaves that are included in employee turnover only includes natural turnover (resignation, termination, retirement etc).
It does not reflect any redundancies. Planned redundancies are reported and explained separately if relevant for employee turnover.

_________________
EXPLANATION OF VARIABLES AND THEIR RELATIONSHIP WITH EMPLOYEE TURNOVER
1- Salary:Salary is remuneration or amount of money paid to workers or employees for their services and is measured on monthly basis not hourly as in wages.
Affect:
Less salary causes Employee Turnover.
2- Performance appraisals:Performance appraisal is sort of method by which the job performance is evaluated in tern of quality, quantity, cost and time through which employee’s success or failure is analyzed.
Affect:
Low performance appraisals cause Employee Turnover.
3- Working environment:A work environment can be identified as the place that one works. i.e. in an office building in cabin, at home at the kitchen table, from a car or truck, at a construction site. All are work environments.Affect:
Bad working environment causes Employee Turnover.
4- Employee motivation:Motivation refers to the initiation, direction, intensity and determination of human behavior.
Affect:
Lack of employee motivation causes Employee Turnover.
5- Personal growth:Employee’s responsibilities in the organization should help them achieve their personal goals. Organizations cannot keep aside the individual goals of employees and foster/promote organizations goals. Employees’ priority is to work for them and later on comes the organization. If they are not satisfied with their growth, they will not be able to contribute in organization’s growth.
Affect:
Lack of personal growth causes Employee Turnover.
6- Employee management:Employee Management means to provide guidance to employees in order to examine internal control and to avoid fraud.
Affect:
Poor employee management causes Employee Turnover.
7- Job Satisfaction:Job satisfaction describes how content an individual is with his or her job. According to my perspective happier people are more satisfied with their jobs.
Affect:
Less job satisfaction causes Employee Turnover.
8- Promotional Opportunities: Promotional opportunities mean encouragement of growth or progress. And due to effective and efficient work employees are given promotional opportunities.
Affect:
But Less Promotional opportunities cause Employee Turnover.
9- Matching jobs to people:Matching jobs to people needs proper management skills to organize their organization by putting right persons on right jobs e.g. division of managers according to their skills.
Affect:
Less matching jobs to people cause Employee Turnover.
10- Staff training and development:Staff training and development plays a vital role in introducing new concepts e.g. bringing an advance mode computer system in an organization or introducing new software’s requires proper training of staff.
Affect:
Less or not appropriate staff training and development cause Employee Turnover
11- Team working:Team working means managing people to see that they get the work done satisfactory. Remember, managers are not paid to have all the ideas that are necessary to keep their section working well, but they are paid to make sure that there are enough ideas to make things work and go on working.
Affect:
Less team working cause Employee Turnover
12- Incentives:An incentive can be in term of bonus or an additional payment to employees for high productivity. It is a sort of motivation.Affect:
But less incentives cause Employee Turnover.

INTERPRETATION:
The equation of the fitted model is

+ 0.0514776*X10
The R-Squared statistic indicates that the model as fitted
explains 33.6858% of the variability in Y. The standard error of the estimate shows the standard deviation of the residuals to be 0.610156. Since the P-value in the ANOVA table is greater or equal to 0.10, there is not a statistically significant relationship between the variables at the 90% or higher confidence level.

Comparison of multiple and individual variables analysis on the basis of model and theoretical significance.
Y = a + bx2 + cx3 + dx4 + ex5 + fx6
Whereas y is dependent variable (Employee turnover) and independent variables X2 (Performance appraisal), X3 (Working environment), X4 (Employee motivation), X5 (Job satisfaction), X6 (Promotional opportunities).
The above equation is being generated by making brief analysis of 10 variables and the above 5 variables are selected as best among 10 just because of their p-value (The probability of accepting null hypothesis). Which are found less than other variables.
Overall analysis shows that performance appraisal, working environment, employee motivation, job satisfaction, and promotional opportunities affect employee turnover.
