Top 3 Factors
Salary
The data finds that those in the age group with the highest attrition
(26-35 year olds) are also those with the lowest salary, particularly
lowest average hourly rate. This is not a coincidence as employees seek
a high salary regardless of years of experience, and it's not surprising
the 1st, 3rd and 4th highest attrition job roles are also those with the 3
lowest salaries.
Overtime Hours
The people who have to work the most overtime hours are also those
who have the highest attrition, and attrition numbers only go down
when overtime hours go down. It's clear from the data that those who
live closest to office get the most overtime hours, and those are the
people who have the highest attrition regardless of living close to the
Top 3 Recommendations

company are not looking to stay there for the long run, with a huge factor
being a low salary, hence they leave to search for another job with better

longer and decrease attrition.
- Less overtime hours. The data shows that most likely, those staying close
by to the office are being made to do more overtime, hence this needs to
change, and one way is to set a company-wide rule to limit overtime hours
to a certain number and should not exceed that. Better work-life
balance=more satisfied employees=less attrition.
- Speaking of satisfied employees, it is apparent that since the people who
have the highest attrition also have at least 1 year experience in another
company they might compare work life in this company to others and find
