English to Polish Bus/Financial Management

This year, we benchmarked several
companies that were focusing on sales
staff retention. For example, a publishing
firm has a program that allows the
top 10% of its reps (based on the previous
year’s performance) to hire their
own administrative people for the coming
year and bill the firm for the expense.
This makes these stars even more
productive and has brought their turnover
rate down to 0%.

Czego może dotyczyć turnover rate w przypadku sales repów???
