We were using Google Calendar for our schedule management but realized that we couldn't see who was working from home or if they had any vacation time left over after their shift! It's been such great help because I can now know exactly when each person will have free days before my shifts start (and even better knowing what holidays fall during those weeks). Also being able realize which people are available at certain times has made things easier as well since there aren’t tons of emails back n forth every day about availability issues etc...
