Exiting out of nested switch statement to outer switch statement

I've created a menu in Java wherein each option has another menu. I want to know if I can exit from the inner menu back to the main menu.

Edit: Added Main Menu options

System.out.println("Main Menu");
    System.out.println("1. Hourly Employees");
    System.out.println("2. Salary Employees");
    System.out.println("3. Commission Employees");
    System.out.println("4. Weekly Calculations");
    System.out.println("5. Exit Program");
while(true){
    switch(choice){
        case 1: 
            HourlyEmployeeChoice HEC = new HourlyEmployeeChoice();
            //HourlyEmployeeChoice is a class with HEmployeeMenu() method 
            HEC.HEmployeeMenu();
            break;
        //case 2-4: to be added later
        case 5:
            System.out.println("Goodbye!");
            System.exit(0);
    }
    }

This is my main menu. I only wrote the code for the first option and the option to exit.

public void HEmployeeMenu(){
    while(true){
        //submenu options
        int hourlyChoice = userChoice.nextInt();
            switch(hourlyChoice) {
                case 1: 
                    //code
                    break;
                case 2: 
                    //code
                    break;
                case 3:
                    //code
                    break;
                case 4: //exit submenu
                    return;
                default:
                    System.out.println("Please make a valid selection"); 
            }
    }
}

This is the method I put my second switch statement inside. Choosing option 4 (exit submenu) refreshes to the submenu rather than the main menu. I think what's causing this is the while loop I have for the submenu. I don't want to take this option off though, because I want to be able to continue making choices after doing cases 1-3.

I believe the problem you are having is

while(true){
  // HERE
  switch(choice){

You need to add code to get the choice again, otherwise it will always be whatever you first entered.

That is move the main menu display and choice input to something like

while(true){
  System.out.println("Main Menu"); // <-- Added based on your edit.
  System.out.println("1. Hourly Employees");
  System.out.println("2. Salary Employees");
  System.out.println("3. Commission Employees");
  System.out.println("4. Weekly Calculations");
  System.out.println("5. Exit Program");
  int choice = userChoice.nextInt(); // <-- HERE
  switch(choice){
