Use cases

  • Not every employee is equipped with a company email address. Thanks to Threema Work, however, everyone can be reached, no matter in which branch of the hotel they work.
  • Flexible usage: The various departments use different features of the app in the way that suits their needs best. There is a separate group chat for each department, and they are all used actively.
  • Accessible anywhere: Even in rooms where the mobile network’s signal is weak, Threema Work can be used to make phone calls over the Wi-Fi network.
  • Threema Work is also used for communication with external parties.
