The crux of the matter:
To arrange a vacation, you need to agree with your supervisor, write an application, get approval from managers, and so on...
In some countries, for instance, each employee MUST go on vacation at least twice a year. In a company of 50 employees, that is at least 100 vacations to be arranged per year. There are documents flying all over the place, some of which get mixed up and lost.
Other employees do not know who is going on vacation and when. They only find out when they need the employee’s input and they’re nowhere to be found.
But, there’s good news - We’ve devised a method to prevent all this!
