Do you like having a cup of coffee in the morning? If so, design your morning so that you leave early enough to treat yourself to a cup AT WORK. Worse case, you'll miss your cup of coffee if you are late....but you will always be able to punch on time!!

Re: sharing your dx with your manager.....I wouldn't. Like you said, once done there is no going back. Yes, you could tell, keep accurate records, and build on EEOC case if you feel you can prove discrimination. However, EEOC cases are an extremely difficult undertaking, full of stress, and corporations usually manage to out spend and out last the employee.

Whatever method you decide on - - I hope it works like a charm.
