No, not on your work email on your financial life. Let your banking institutions and credit card issuers know where you are going and when. Fraud protection is great, until you learn that your credit card company can not picture you on safari and suspends your card mid trip. Also take a few minutes to photocopy your passport, drivers license, plane tickets, and credit cards, and leave those papers with someone not lucky enough to go with you. You may also want to pay your bills early to avoid accidentally missing the due dates.
