In Slovakia a much larger share of service workers know three or more foreign languages than the EU average. For contact centres that is both an asset and a training task: a new operator learns the product and the systems, and also how to handle a difficult call in a language that is not their own. This guide sums up what European statistics and the EU occupation classification ESCO say about the sector, and what follows for training.
How the sector is structured
As elsewhere in the EU, there are two kinds of contact centre, and the statistics count them differently.
- In-house teams. A bank, telecom operator, energy company or online shop runs its own line. Its staff are counted in the parent company's industry.
- Outsourced providers. A specialist company handles calls for other firms. In the SK NACE classification this is class 82.2, call centre activities.
Eurostat's structural business statistics show only 24 enterprises in class 82.2 in Slovakia in 2024, with 2,561 persons employed (2021: 22 enterprises, 2,504 persons). The average firm therefore has more than a hundred people. Outsourcing here is not split across hundreds of micro firms as in Poland; it consists of a few dozen larger firms.
Most people work in in-house teams. The EU Labour Force Survey counts 27,700 people employed in ISCO sub-major group 42, customer services clerks, in Slovakia in 2024 (2022: 25,800). The group includes contact centre clerks as well as receptionists, enquiry clerks and travel consultants, so it is not an exact operator headcount. Telephone sales sit in a separate group (ISCO 5244).
Languages served
Slovak is the base language, and the language base is relatively strong. In Eurostat's Adult Education Survey (2022), 12.6% of Slovak clerical, service and sales workers aged 25 to 64 knew no foreign language, against an EU average of 23.5%. 20.2% knew three or more, against 11.3% in the EU.
For training this means two things. An operator with three languages can work across several projects. And in each language they need ready phrases for the hard moments: the apology, the explanation and the proposed fix.
Roles and career paths
ESCO follows the international ISCO-08 classification and gives the role names in Slovak:
| Step | Role (ESCO) | ISCO-08 group |
|---|---|---|
| Entry | Call centre agent (telephone sales and telemarketing) | 5244 |
| Entry | Customer contact centre information clerk (service and information) | 4222 |
| Specialist | Call centre quality auditor, call centre analyst | 3341 |
| Team lead | Contact centre supervisor, call centre supervisor | 3341 |
| Management | Contact centre manager | 1439 |
Following these roles, the path runs from operator through quality control or analytics to team leadership. Operators with several languages have an advantage on that path, because they can assess and coach calls in more than one language.
Training challenges
Switching languages. An operator who alternates between calls in two languages needs a set of fixed phrases in each one. Under stress, the wrong-language word comes first.
Fewer firms train. In the 2020 Continuing Vocational Training Survey, 58.9% of Slovak enterprises provided training, below the EU average of 67.4%. Participants spent 16.3 hours in courses on average (EU: 22.5 hours; 2020 was affected by the pandemic). Call practice often falls to the team lead.
A complaint in a foreign language. Many people manage an everyday conversation. Far fewer manage an angry customer who speaks fast and interrupts in a foreign language. That can only be trained out loud.
Large projects, fast ramp-up. When an outsourced firm has more than a hundred people, a new project can mean a whole group of new starters at once. A supervisor has no time to listen to ten trial calls from each of them.
One line to practise
For a customer who is angry and will not let you finish:
"I can hear this has really upset you. Let me repeat what happened so I can fix it properly the first time."
Say it out loud five times in Slovak, then in the language you call in most.
Practising these calls with DIRI AI
With DIRI AI an operator practises a call by voice with an AI customer that is clearly labelled as AI and fictional, then reads a report on what to say better. It works in 11 languages, so a team can rehearse the same call in Slovak and in a foreign language. There is a Free plan; see the pricing page.
