It would be nice to have a calendar system that displays the schedules of all of my employees, as well as any scheduled off or PTO time.
Any sick time, PTO, and vacation time should be included in the calendar with calculated totals of available time.
So vacation time could be: Time accrued - time used = Total time available
PTO and Sick days could be the same, each company could put their own numbers into that formula as a start to display available time and time used to employees.
It would also be nice to show scheduled PTO in the calendar.
Also, an accrual system would be legit: time period of accrual(hours, months, years, etc) + accrual amount = total time accrued.
It also seems like those would be generic enough formulas, that any companies could use them just by inputting the info.
