His family had paid €7,500 in agency fees and another €11,300 for language courses, housing and other requirements. After colleagues warned him of exploitation, Bau taught himself German labour law, received help from a hospitality union, sued his former employer for excessive overtime and won.

The victory let Bau move to a new hotel, finish his training with top marks, become a shift supervisor and earn three times his previous salary. In 2024 he and two former trainees founded a recruitment company that charges German employers €5,000 per successful placement, removing agency fees for Vietnamese candidates.

23‑year‑old Thu Trang faced a different struggle at a Leipzig hospital. Colleagues gave her tasks outside her nursing programme, bullied her and blocked learning opportunities. She kept a notebook of medical terms, translated Vietnamese material into German, and practiced daily. As her language improved, she began refusing unreasonable work and says speaking up earned her respect.

Overall, more than 16,000 Vietnamese are enrolled in German vocational training, according to the 2024 Migration Report. Many lack strong German and are unfamiliar with labour rights, which makes them vulnerable. Christopher Gnadt, a lecturer at the University of Vechta, says weak German and timidity often put Vietnamese workers at a disadvantage: “German employers do not expect an employee who simply knows how to obey,” he says. “Timidity and reluctance to ask questions are often perceived as lack of competence.”

Nguyen Thi Loan, now a practical instructor and support‑hotline operator, illustrates the long‑term impact of language mastery. She says using German every day with her husband’s family helped her integrate fully. “I have a voice and the right to determine my own future,” she says, describing true integration.

These stories show that learning German, understanding labour law and asserting one’s rights can protect migrants from exploitation and open pathways to skilled careers.
