Early in my career I lived up to the mantra “work hard, play hard.” There were many days when I would come into the office after a late night of eating, drinking and being merry. Of course, when you don’t get enough sleep, and calling in sick is not an option (I don’t know about most of you but I save up at least some of my sick days for the purpose of recovery) it is important to know how to come into the office looking fabulous, and most importantly professional (and have it not interfere with your job performance).
If you are coming in from a flight, you can use the excuse of an airport delay (since it happens to everyone). Go home and freshen up and head in late. Just make sure you turn off your cellphone, so it doesn’t give you away in the event someone calls looking for you. You should also plan on being the last to leave the office, so pack plenty of caffiene.
If it was just a late night then head in, large sunglasses in tow and let your colleagues know you are feeling a bit under the weather. Clear your calendar of all non-essential meetings–afterall it isn’t like you can make important decisions in your condition. Try to prioritize tasks you don’t normally get to but may not require a lot of will power–filing, cleaning your desk, returning phone calls or emails, writing thank you notes. At least that way part of yoru day will be productive. Drink some tea and eat healthy foods (helps with recovery). Finally try to get out of the office a little early and get some rest, you will need to compensate for your lost day tomorrow.
