Research has shown that very often people in the workplace will not approach their Manager, Team Leader or Employer when they need further training but they will speak to a colleague over a cup of coffee or in passing.
Usually it is because they feel that by speaking to their Manager, Team leader or Employer they will be perceived as having a weakness and possibly are not up to the job. So they carry on doing what they have always done, they do not address their concerns and do not achieve their full potential.
Often people are underperforming and not reaching their true potential, which in turn means that they are not doing as much for your business as they could be.
In some cases it means that mistakes are made that can cost the organisation money!
