Following on from my last share, I strongly suggest employers and managers consider organising speechcraft (speech and speaking development) go go programs for employees. These sorts of programs are available and information can be sourced from online inquiry.
While there may be some cost associated with such programs, employees will be appreciative. Their development of speaking and listening skills will enhance the organisation because of the enhanced way they present to those making contact with the company.
First impressions are lasting impressions. The way in which customers and potential clients are greeted can value add to (your) organisation. In that context, everyone is a winner.
