To ensure proper staffing during the product launch period, Sales personnel planning to take approved time off are encouraged to schedule their vacations before June 15 or after July 15 to participate in the iPhone launch.
Previously approved vacation will be allowed where voluntary rescheduling is not feasible
No additional vacation requests will be approved during the launch period (6/15 – 7/15).
Med andra ord: iPhone-lanseringen är en "big deal" och folk måste finnas på plats när revolutionen startar
