when you send an email to a manager that does not reply with a satisfactory answer you can email their superior with any complaint about them. the trick is to 'cc' a copy to the personal file of the original manager and 'bcc' a copy back to your own email address. this can be particularly handy if in future you initiate harassment/discrimination claim against manager plus it also looks very bad on their personal file. suddenly you will find your manager no longer wants to know you even exist. .....mindf***ing in reverse!
