Change name of a tab for a specific content type
You can use hook_menu_alter() to change the name of tabs for a specific content type. For example:

/**
 * Implements hook_menu_alter().
 */
function MYMODULE_menu_alter(&amp;$items) {
  unset($items['node/%node/view']['title']);
  $items['node/%node/view']['title callback'] = 'MYMODULE_view_tab_title';
  $items['node/%node/view']['title arguments'] = array(1);
}

function MYMODULE_view_tab_title($node) {
  if ($node-&gt;type == 'organization') {
    return t('Organization Home');
  }
  return t('View');
}
