location.reload(false);

This method takes an optional parameter which by default is set to false. If set to true, the browser will do a complete page refresh from the server and not from the cached version of the page.

If you are using react-router v5, you can use useHistory hook

const EmployeesList = () => {
  const history = useHistory();
  const reload = () => {
    history.go(0);
  }
}

If you are using react-router v6, you can use useNavigate hook

const EmployeesList = () => {
  const navigate= useNavigate();
  const reload = () => {
    navigate(0);
  }
}

However, consider if you really need to reload the page or if you can rerender your components without reloading the page

You can use react useEffect depencies to auto reload the information of employees

Like this...

import { Link } from "react-router-dom";
import Swal from "sweetalert2";  

const EmployeesList = () => {

const[employees, setEmployees] =  useState([]);

const[deleted,setDeleted ] =  useState(1);

  useEffect(() => {
    init();
  },[deleted])

  const init = () => {
    employeeService.getAll()
    .then(response => {
      setEmployees(response.data);
      setDeleted(prev=>prev+1) 
    })
    .catch(error => {
      console.log('Something wrong', error);
    })
  }

  const deleteSweetAlert = (id) => {
    Swal.fire({  
      title: 'Are you sure?',  
      text: 'User will have Admin Privileges',  
      icon: 'warning',  
      showCancelButton: true,  
      confirmButtonColor: '#3085d6',  
      cancelButtonColor: '#d33',  
      confirmButtonText: 'Yes!'  
    }).then(result => { 
        if(result.value) {
          employeeService.remove(id);
          init();
        }
      })
      .catch(error =>{
        console.log('something wrong ',error);
    })
  }

In react useEffect() hook get called very first time & the depencies passed to useEffect changes

Its is a dirty trick to make this automate
