Why not to take the date from employees date the hire date in our case

Hi Islam!

Thanks for reaching out.

Are you referring to the 'hire_date' column from the 'employees' data table, please? If this is the question, please refer to the second task we solve in the course (i.e. Problem #2), where we create the 'active' column to deal with the issue.
Of course, feel free to get back to us should you have further questions. Thank you.

Hope this helps.
Kind regards,
Martin
