What is an Employer of Record and how does it work in the United Arab Emirates?

I have been researching about Employer of Record (EOR), and I would like to know how it works in the United Arab Emirates, especially if you are planning to hire remotely.

From what I have learned so far, Employer of Record is essentially a service provider that assumes the role of the employer for employees sourced by an overseas company. In other words, while the overseas company would be responsible for managing the employee’s output or work, the EOR service provider would be in charge of all other matters regarding the employee.

I would like to know if any of you have used EOR in the UAE before. I would like to know how smooth it really is in real-life situations.
