How to alter the visibility of a menu tab for a page created in Views?
I created a mini module called helper.

In helper.info I put

name = "Helper"
description = "Provides custom support functions."
core = "7.x"


First we need to get the helper_menu_alter() to be called after views_menu_alter so we use hook_module_implements_alter to pull the value of our module in the array and put it back in which will always be done at the end of the array.

&lt;?php

function helper_menu_alter(&amp;$items){
  $items['user/%/workbench']['access callback'] = 'helper_access';
  $items['user/%/workbench']['access arguments'] = array(1);
  $items['user/%/workbench/drafts']['access callback'] = 'helper_access';
  $items['user/%/workbench/drafts']['access arguments'] = array(1);
  $items['user/%/workbench/needs-review']['access callback'] = 'helper_access';
  $items['user/%/workbench/needs-review']['access arguments'] = array(1);
}

/**
 * Helper access callback.
 */
function helper_access($uid) {
  if ($uid) {
    if ($GLOBALS['user']-&gt;uid == $uid || user_access('view all unpublished content')) {
      return TRUE;
    }
  }
  return FALSE;
}

function helper_module_implements_alter(&amp;$implementations, $hook) {
  if ($hook == 'menu_alter') {
    // Move helper_menu_alter() to the end of the list. module_implements()
    // iterates through $implementations with a foreach loop which PHP iterates
    // in the order that the items were added, so to move an item to the end of
    // the array, we remove it and then add it.
    $group = $implementations['helper'];
    unset($implementations['helper']);
    $implementations['helper'] = $group;
  }
}
