Human Resources Dashboard

Hello guys, I'm setting up a dashboard for my company and I have a question.

I have to put together a graph showing which team leaders have more than one employee vs the leaders who are "alone" with no team. I have to answer the following question: how many subordinates does each leader have?

For this I have two tables: one with the movement of employees and another with the period that each employee was a leader.

I forward the attachment with this data.

movement 

leaders
