What is the best practice for removing old employees workforce without losing the data?

Summary:

Content (please ensure you mask any confidential information):

I am looking for a good way to remove old employees from workforce so that we don't keep growing the employee dimension, while still maintaining the historical totals. This is needed because we have high turnover rates in some departments and if we don't clean this up every year, the employee dimension will accumulate far too many members. What are some suggestions on how to do this?
