What is the number of temporary employees or interns in the company during a certain period?

To determine the number of temporary employees or interns over a specific period, data is usually obtained from HR systems or the company's database. For example, you can write an SQL query that selects all employees with employment type 'temporary' or 'intern' and working dates overlapping with the desired period. In Python, this can be automated using libraries for database interaction, such as pandas for analyzing exported data.
