I recently received this question…
It has been about 5 years since we trained, what is the best method to restart.
After a few years, the best way to restart a training initiative is to consider it as though you had not done any training, or a fresh start. This recommendation is because the previous training initiative has fallen through the cracks and some time has passed… your employees are almost always in the need of either retraining or a refresher.
There is always an excuse to not train your employees, but it is never bad time to start training, or to restart a training initiative.
