Handle Your Workload in Advance
No one likes a slacker, particularly if she comes back from vacation tanned and blissed-out. Avoid becoming the office pariah by tying up projects and other loose ends before you check out for your wedding. Discuss your workload with your boss and co-workers, and divvy up tasks that must be handled while you're out for the wedding and honeymoon. Inform everyone who will be even a little bit impacted by your absence, and give them the name of the person they can turn to if necessary.
