Altough your description is very little,
I give you a really simple guide on how to do this:
First thing, opening a form on click is a javascript thing so the first thing you need to do is add your JavaScript file,
let's assume you have a file assets/js/register.js which looks like this:
var btn = document.querySelector('button.my-register-button');
btn.addEventListener('click', function(e) {
e.preventDefault();
document.querySelector('#my_registration_popup').style.display = 'block';
});
Then we need to add this file to wp_enqueue_scripts action in order to be added to Wordpress pages
add_action('wp_enqueue_scripts', function() {
wp_register_script('my-registration-plugin', YOUR_PLUGIN_URL . '/assets/js/register.js', [], null, true);
});
assuming that your register-employee.php file looks something like this:
<div id="my_registration_popup" style="display: none">
<!-- my form -->
</div>
First thing you need to do is to add above view to wp_footer action:
add_action('wp_footer', function() {
include PATH_TO_YOUR_PLUGIN . '/view/register-employee.php';
});
