Fetch custom post related to a User

I am trying to fetch custom post related to a User. I am using below code.

$args = array(
			'post_type' 	=> 'tasks',
			'meta_query' 	=> array(
				'relation'  => 'AND',
				array(
					'key' => 'users',
					'id' => $user->ID,
					'compare' => '=',
				),
			),
		);

		$query = new WP_Query($args);
		$posts = $query->posts;

But I am not getting any output.
