Lolz, if you are not testing an employee that you are employing into your business or the manager and other staff,you could employ someone with less qualification that is necessary to run the business and this can reduce your business productivity.I am glad that I can be of help and I can see that I have also learnt in lunch from you because there is no way that anyone knows it all. It is very important that once needs to test their employees before they can be fully employed so that they can be tested to know they are ability to do the work well.
