Customs raid in Karlsruhe: illegal work on construction sites uncovered!
On Monday, June 16, 2025, customs in Germany carried out extensive controls against undeclared work and illegal employment on construction sites. Over 2,800 customs officers were deployed across the country, including 116 in the Karlsruhe area. bnn.de reports on a consistent review of compliance with legal regulations in the construction industry.
The officers checked in various cities, including Heidelberg and Rastatt. Particular attention was paid to the registration of employees with social security, the receipt of illegal social benefits and compliance with the minimum wage. 88 people were interviewed at construction sites in Karlsruhe and business documents were checked four times. These measures led to six criminal proceedings being initiated and two administrative offense proceedings, including those based on illegal residence. Surprisingly, two people tried to evade control but were quickly caught. In addition, one person was arrested because there was an arrest warrant.
Nationwide raid
These controls are part of a nationwide campaign that also takes place in metropolises such as Cologne, Berlin and Munich. For example, at a construction site for a rehabilitation center in Bornheim, 27 men were checked, five of whom were employed illegally. Originally from Belarus and Kosovo, those affected now have to expect legal consequences. It is suspected that they were paid below the minimum wage, reflecting the humble reality of many workers in the industry. [spiegel.de].
Customs is very targeted in its investigations and checks that foreign workers are correctly registered. It is determined whether they are legally employed. In addition, the workers should receive at least the legal minimum wage of 12.82 euros per hour - which is a much-discussed topic in the construction industry. These requirements are often a challenge, which tagesschau.de describes in detail.
A far-reaching problem
The construction industry is known for its diverse challenges, particularly with regard to combating undeclared work. The latest raids are a clear sign that the state is not only complying with the legal framework, but is also actively taking action against abuses that not only endanger fair competition, but also affect the rights of workers. It remains to be seen what further measures will be taken to sustainably improve conditions in the construction industry.
Overall, these control operations show that solidarity with legally employed workers is strong and that the authorities will continue to support this development. The colorful construction sites in Germany could soon lose some of the dark shadows of undeclared work if customs continues to act with such determination.
