Three Strikes And You're Out

Please, please remember that you definitely need voicemail to field calls when you are not available. Most managers will give up after three failed attempts. Even if they do get through to you on the second or third try, days or even weeks may have passed since the first attempt. Almost all managers have grown accustomed to "phone tag" and will gladly pass the baton back to you, possibly even giving you their direct line and the best time to reach them.
