Employees are not showing

When I am going in employees , it is not showing all the employee list as shown in image. how to resolve it? and how to give access to user to see all employee list from admin end

I believe you have some restrictions to see the list. check your user role permissions.

which permissions I have to set for this?

Login in as Administrator and check the role permissions assigned to the user which is currently using to view the employee list. Assuming you are not logged in as Administrator at the moment.

maybe this page will help you to get more details about role permissions.
