I have an employee who has been working in payroll and purchasing for 2 years with little to no incidents. However, lately there has been a constant stream of mistakes; one in particular required deleting the whole payroll and rekeying it by hand. It is like this employee went home one day and came back the next day and forgot all the knowledge they had obtained. I have this person work from their manuals in order to avoid further incidence. Any suggestions on what on earth is going on?
You can read my answer to this question — and four others — over at Inc. today, where I’m revisiting letters that have been buried in the archives here from years ago (and often updating/expanding my answers to them).
