Google faces another antitrust battle in Europe.
23 job search firms have written to the European Commission asking it to take action.
In a letter seen by Reuters, they claim the search giant is abusing its dominance to drive users to its own offering.
Signatories include Germany's Intermedia and Jobindex.
Google's job search widget pops up alongside relevant searches in many countries.
It aggregates listings, though users must go elsewhere to actually apply.
Rivals say it benefits by gaining traffic from searches, without having to spend on marketing.
The letter lands on the desk of Competition Commissioner Margrethe Vestager.
And she's got a history of ruling against Google - not least a 5 billion dollar fine in 2018 for using its Android mobile operating system to squeeze out rivals.
Now Vestager is due to leave office on October 31.
But there may be little comfort in that for Google.
Commission insiders say she has prepared an "intensive" handover for her successor.
