The employee can't afford the expert fee. What is the best solution?

Hello,

When an employee filed a case against a company about some pending salaries and because of some complications in the case about the calculations, the court ordered to hire an accountant expert and all expert fees the employee has to pay.

Here I have some questions please answer:

- If the employee can't afford the expert fee, what is the best solution?

- If the employee pays for the expert fees, later, will he get back this cost?

- If the employee refused to hire an expert, what will be the negative impact on his case?

Thank you!
