Would you work for nothing? Non-paid internships(实习生) have been common in the US for some time now. But these days, they are becoming more and more popular in other countries, too. Is this a good thing?

For young people, there are clear benefits to doing an internship. Firstly, interns get a valuable insight into an industry they might be interested in working for. Also, having done an internship looks good on your CV, which is very important in today’s competitive job market. A lucky few may be hired at the end of the internship, so it’s a good way of getting a foot in the door. For other interns, there is even extra welfare: deals on clothes if they’re working in the fashion in industry, free trips if they’re working for a travel agency…and so on.

There are obvious benefits to companies, too. They can help select employees who are better. “If you put two young people to work as interns for twelve weeks, you’ll soon see who is good.” said one manager. Besides, they can save money. “If I use interns, I don’t have to pay another salary, or worry about paying pensions or giving people overtime pay.” said another.

So, what do interns do? Most tasks are fairly routine. These may include photocopying, filing documents, or writing up notes from meetings. At times, interns may be given jobs with more responsibility, such as making sales calls, writing newsletters or updating websites.

However, for some interns the experience can become unpleasant. “I worked for a theatre company for six weeks and spent the whole time photocopying scripts and making the tea and coffee. It is dull.” said one intern. On the other hand, non-paid internships violate the labor law in some countries, where workers must be paid the minimum wage and paid for overtime.

Internship can provide benefits to both sides, but these unpaid workers are also easy to take advantage of!
