It was a bit frightening, if you were like most kids. Lots of new people and a completely different environment. You weren't quite sure how you would be accepted.
New employees feel much the same way.
They are coming into a new environment, meeting new people, and are not sure how they will be accepted. Employers can ease the transition and take advantage of the opportunity to get the relationship off to a good start. Welcome your new employee. Smile, and tell them you are glad that they have come to work in your establishment. You can make a big difference at this point.
