We will work with exit surveys from employees of the Department of Education, Training and Employment (DETE) and the Technical and Further Education (TAFE) institute in Queensland, Australia
In this project we will try to answer the following questions:
Are employees who only worked for the institutes for a short period of time resigning due to some kind of dissatisfaction? What about employees who have been there longer?
Are younger employees resigning due to some kind of dissatisfaction? What about older employees?

Looking at the initial data I have the following observations:
DETE SURVEY
Aboriginal 806 Torres Strait 819 South Sea 815 Disability 799 NESB 790 Business Unit 696
Most of the columns are string or boolean variables. For the string vaiables it would mean that we will have better understand if this fields are going to be useful for our objective. If they are we will have to define specific transformation to extract value out of the data.
The ID field seems to be working more of an index instead of the true ID of the customer.
Some of the fields are string characters that hold numerical ranges. This fields will have to be transformed so they can be of any use.
TAFE SURVEY
The data columns have very long names composed in the form of questions, which we will have to shorten to understand the value we can extract from each one.
The ID field is composed of a float type variabl
Most of the columns are string variables. This would mean that we will have better understand if this fields are going to be useful for our objective. If they are we will have to define specific transformation to extract value out of the data.
This dataset has more missing values across the board

In cell 11 we went back and changed the values that appeared as Not Stated to NaN values so that they can be identified as missing values.
In the last two cells we removed columns from both datasets that were not going to add any value to determine our objective.

After removing the unnecessary columns on both datasets I proceeded to standarize the format for the names on the columns of the the DETE SURVEY dataset, and the shorten the names of the columns that would be most useful in the TAFE SURVEY dataset.

To try to answer the original question: Are employees who have only worked for the institutes for a short period of time resigning due to some kind of dissatisfaction? What about employees who have been at the job longer? We will have to infer the years of service from the substraction between the dete_start_date and cease_date for the Dete_resignations data set.
dete_resignations['institute_service'] = dete_resignations['cease_date']-dete_resignations['dete_start_date']

Now that we have added the column for years of service we have to determine if the REASON for resignation was due to job dissatisfaction. For this we are going to classify on both data sets the dissatisfaction reasons and create a column called dissatisfaction to classify our results.

To continue trying to answer our original question we based our analysis in the study published in Business Wire were it stated that employees should be assesed according to the career stage in which they are at. According to this article there are 4 categories:
We used the column institute_service and converted to a float to categorize each employee in a new column called service_cat.

By doing a bivariate analysis between service category and dissatisfied employees, I come to the conclusion that 68.5% of the resignations were from employees with more than 7 years in the institute (68.5% from established employees and 43.7% from veteran employees). With this data we can infer that people that work in the DETE and TAFE institute become unmotivated with their jobs probably because of the few challenges they are facing.
