Even with PHP plugin get_posts not working in widget area

Tuns out it needed: global $post

Complete working code:

<div class="aboutgridcont">
<ul class="about-us-grid">
<li>

<?php
global $post;
$posts = get_posts('post_type=employee&orderby=rand&numberposts=16'); foreach($posts as $post) { ?>

<img  class="headshot" src="https://wordpress.stackexchange.com/questions/196622/<?php the_field("headshot'); ?>">

    <?php } ?>
</ul>

  </div>
