how to use second middleware

When attempting to log in through the new login page, it should connect to the new middleware named 'EmployerMiddleware.' However, it continues to display the message 'These credentials do not match our records' on the login form. Upon investigation, I discovered that instead of checking the credentials in the 'employer_information' table, it persists in checking if the email and password exist in the default 'user' table. How can I correct this within the following code? EmployeerMiddleware.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;
use App\Models\EmployerInformation ;
use Illuminate\Support\Facades\Auth;

class EmployeerMiddleware
{
 
    public function handle(Request $request, Closure $next)
    {
       
        if ($request->has('email') && $request->has('password')) {
            $credentials = $request->only('email', 'password');
            if (Auth::guard('employers')->attempt($credentials)) {
                // Authentication passed...
                return $next($request);
            } else {
                // Authentication failed...
                dd('Authentication failed'); // Debugging statement
            }
        

        }
        return redirect()->route('empLogin')->withErrors(['email' => 'Invalid credentials']);
    }
}
