In addition to his full-time job at ISS, Kacper is a professional rugby player. And his athletic career is impressive: four seasons in Poland, four in England, one in Portugal, twelve in France - and three in Switzerland so far. He has also made 35 appearances for the Polish national team.
These various experiences have made the 39-year-old a natural with languages, which stands him in good stead at work.
“I enjoy interacting with my colleagues. We speak English, French, and some of them also speak Polish,” he says. Kacper has been working in ISS’s moving services for six years, and here, too, he’s a true team player: “I like that my job is so varied, and I’m happy to step in for my colleagues.”

Kacper trains twice a week with the team, plus he does two strength training sessions and spends time with his six-year-old son: “I go biking or play soccer with him. Two years ago, he started playing baby rugby and is now on the U8 team,” he says proudly. His daughter has inherited his talent for languages: “She’s 17, is more interested in books, and already speaks four languages.”
When Yverdon-les-Bains poached Kacper and a few teammates from Pontarlier, rugby wasn’t yet very popular in the region. “With the newly formed team, we became champions right away, which of course makes the sport more attractive.” Now a few hundred spectators come to the matches - and sometimes among them is an ISS colleague who comes with his family to cheer on Kacper.
He definitely wants to keep playing next season; after that, he’ll take it year by year. He’s starting to feel his age: He used to play the full 80 minutes, but now he only plays about 65. “Luckily, the matches are on Saturdays. That way, I can recover on Sundays and be fit for work again on Monday,” he says with a laugh.
