Are all of these stats on a monthly basis?
I'm not sure how to calculate some of these in terms of your process, so you will have to help out.
Total number of staff on vacation Do you mean how many have taken at least 1 day of vacation or off for the whole month?
Total number of vacation days accumulated for the month Do you mean accumulate the time taken as vac time for the month or do you want the total of vac time that still has not been used?
Total number of officers on vacation? Do you mean the total number of different officers who took at least 1 day of vacation during the month?
Total number of civilians on vacation Same as above
Average number of staff on vacation per day An example would be good
Peak day and number of persons (Day with the most persons on vacation and total for that day)
Minimum day and number of persons (day with least persons on vacation and total number for that day)
Accumulated Sick days for the month: Do you mean accumulate the time taken as sick time for the month or do you want the total of sick time that still has not been used
Number of officers on sick leave For any time during the month? If 1 office takes 1 day off and another takes 2 then each would be treated equally and the count of officers on sick leave would be 2? Or do you want only those on sick leave for the entire month?
Number of civilian on sick leave: Same questions as posed for the officers.
Number of officers on excessive sick leave for the month. Do you mean the number who have exceeded their allocated amounts or do you have a monthly limit as well?
Number of civilians on excessive sick leave for the month Same questions as above
Average number of sick per day: Do you mean accumulate the time taken as sick time for the month or do you want the total of sick time that still has not been used
Peak sick day and number of persons: The one day in a month where the most people were sick? Again do you want it broken down by civilians and officers or combined?
Minimum sick days and number of persons. Not sure what you mean by this.
How do you treat weekends? Is every day considered a work day?
