Joy and pride – 17 apprentices have passed their final exams!

How time flies. It's summer and once again the apprentices at cablex are finishing their training. Fifteen apprentices will continue to work at cablex and actively support our teams.

Three years of training can be very strenuous. The demands on the apprentices are great – exams at school, learning to understand the complex network, working outside on cold winter or hot summer days. 

When we visited Joshua Wiedemann for an interview, he was still working in a shaft. It was hot and felt like 40 degrees under the earth's surface – where you can get a little dirty. But that doesn't bother Joshua, the Italian with a lot of temperament. When we asked Joshua what his highlights were from the past three years of training, his answer came out of the blue: pulling the cables through the Gotthard tunnel. 

I am a very active person, I like tricky tasks that are more complex and need a bit more care and light-fingeredness. If it gets a bit warmer in the summer, I don't mind, the cola tastes even better then. For me it was really cool, because it's not every day you get to see the Gotthard tunnel. These tunnels and these technical rooms, that's something not everyone gets to see. And I had the chance to experience this!

Interview with Joshua Wiedemann.

Elias Baumgartner, a resident of Lucerne, has now received his Federal Certificate of Proficiency at the age of 31. He took the plunge three years ago and started his apprenticeship as a network electrician, with a focus on telecommunications, when he was 28. He's now all the more satisfied that he's chosen this path, and looking forward even more to new opportunities and challenges as a supervising installation technician in the overhead line unit. 

It was a challenge for me, because after all, it had been a while since I last sat in a classroom. As time goes on, it's simply difficult to move ahead without a qualification, you need one these days. That's why I decided to take on the three year apprenticeship. I just wanted to get ahead, to achieve even more.
