That everything within the office runs smoothly, we owe to our 'Ms. Planning': Penny! She is not only the first contact at Onesta (whether by telephone or face-to-face), but she also takes care of the planning and agendas of all colleagues. Is there an appointment that needs to be rescheduled last minute, or are we stuck in the printer with a paper emergency? Thanks to Penny, these problems are solved before you actually realize it. Add to that a good dose of service orientation, and you have penny's winning formula!

Bij aannemen hadden we een functie vrij voor Waakhond, Beveiliger of Hoofd Security, maar na zijn proefperiode blijkt dat de invulling vooral matcht bij Hoofd Welkomstcomité. Harry geeft je een blij ontvangst of maakt tijdens zijn (vaak vrij lange...) pauzes slechts even oogcontact, maar test vooral de ontspanningsmogelijkheden op kantoor. En dat alles maakt hem natuurlijk een onmisbare kracht bij Onesta!
