Thanks!
I think we are good now. Below is the code in case anyone else needs this functionality.
add_action('job_manager_get_listings', 'job_manager_get_listings', 12, 1);
function job_manager_get_listings($query_args)
{
$plan = wc_memberships_get_membership_plans();
if ($plan[0]->slug == 'free-membership-plan' || !is_user_logged_in()) {
global $wpdb;
$query_args['date_query'] = array(
'column' => 'post_date',
'before' => '- 3 days'
);
}
return $query_args;
}
