I've got employee data coming in through our HRIS, and we've got a table that we link to, that provides our location hierarchy. I'd like to add a dynamic column to the merged data that gives me the current turnover for that location. The turnover formula we use is total number of terminations divided by the average number of employees at that location. (Ex. 6 employees have left the shop location, there is a current total of 12 employees at that shop, turnover is 50%).
If anyone has any suggestions for the best way to get this column into the data set, I would be very grateful. I think the turnover calculation needs to be placed on the location and not the employee to allow us to roll up the data through our hierarchy so we can show our market, region, and entire company's turnover.
