Some people see the opportunity to have an intern working for them as a great opportunity for free, or inexpensive workers.
The problem is, that isn’t the purpose of an internship.
An internship is intended to be a learning opportunity for the intern. It should provide the opportunity for the intern to work beside more experienced people and learn from them. It should be a win/win situation where the intern learns and grows and the employer benefits from the interns education and enthusiasm.
If you aren’t willing to create a winning situation for the intern, it would be best for all concerned to not work with an intern at all.
Have a great day!
