Side job | Arno stocks shelves at a huge hardware store
If he could choose absolutely anything, Arno Gankema would rather have a side job at NASA, though with both feet firmly on the ground. Instead, he works at hardware store Hornbach, where he stocks shelves and helps customers. Much sooner than expected, he got his first experience with a mystery shopper.
Arno Gankema is a first-year Psychology & Technology student and, on Fridays and Saturdays, also works as a logistics employee at Hornbach in Tilburg. The store sells tools, decorative materials, garden supplies, sanitary products, and construction materials. His employer expects him to place goods in the correct shelves, but above all to help customers. “Customer service is very important at Hornbach. I’ve already had two training sessions about it.”
In fact, one session would probably have been enough, because even before his first training he had already been “tested.” That means he was visited by a fake customer, an actor hired by the company to report on how well they were helped. It happens often. Gankema heard it takes place about twelve times a month, although he also has a friend who worked there for a year without ever encountering one. The visit from the fake customer resulted in a poor review.
Warm handoff
Arno knows exactly why he received the low rating. “The next day, I learned they pay attention to a warm handoff. You should never leave a customer on their own. Instead, you personally take them to a colleague who can answer the question if you don’t have the necessary knowledge yourself.” The mystery shopper earned him an additional training session, and now he knows the rule very well. “But I also enjoy helping people, and I think I’m doing it right now.”
Hornbach stores are branches of a German parent company and are always very large. The Tilburg store has thirty aisles. Gankema explains why customer satisfaction is such a priority at Hornbach.
“There are fewer Hornbach stores than Gamma, Praxis, or Hubo stores. If a customer drives all the way to Hornbach, they pass three other hardware stores on the way. We have to make it worth the trip, otherwise they won’t come back.”
Outside his own bubble
The student earns one and a half euros more than the minimum wage. That was also the case in the side job he had during the final three years of secondary school, stocking shelves at Jumbo. Alongside playing rugby three times a week, though that’s beside the point. Half of his earnings went toward Pokémon cards, but he has also used the money to pay this year’s TU/e tuition fees and buy a laptop. “I think it’s an easy, pleasant job without any work-related stress. There’s a saying that goes, ‘minimum wage for minimum effort,’ right? Well, that turns out to be true.”
What he enjoys most are the breaks with colleagues, even though many of them, especially on the Friday shift, are at least twenty years older than he is. “That way I get to see a different part of society. I’m used to a path like elementary school, secondary school, university, good job. That’s what the people I know do. But my colleagues have very different lives. We chat with each other, even though they have very strong Brabant accents, haha.”
Long list
Some customers are less enjoyable to deal with. Gankema does not appreciate being challenged after politely explaining that he does not yet have enough knowledge about a particular product. “They’ll say, ‘Why don’t you know that?’ in a rude way.”
“Or they come in with a very long list of things and expect me to point out every single item. I’d never say it out loud, but sometimes I wonder why they don’t just go look for them themselves. Still, I help them with every item.”
You might expect that, surrounded by construction materials and do-it-yourself enthusiasts for twelve hours a week, he has become extremely handy. But that’s not really the case. The most complicated thing he has done in that area was paint a wall in his sister’s room. “A side job at a hardware store isn’t exactly life-changing,” he says matter-of-factly. “I don’t know if I’ll think about it much later in life or whether it will be important for the rest of my life.”
As a reason for quitting, the Tilburg native, who still lives with his parents, can imagine moving into student housing in Eindhoven. Or perhaps getting a side job at NASA that can be done from a computer, because he does not necessarily need to go into space. “No, I’ll keep both feet firmly on the ground.”
