The underlying WHO Europe survey covers the 29 countries of the WHO European Region, which includes non-EU countries, not strictly the European Union as the claim states.
The 'one in three' figure refers to self-reported symptoms of depression or anxiety over the previous two weeks; it is a voluntary, self-selecting online survey, so the prevalence estimate carries the usual response-bias caveats.
The claim's framing of the problems as 'linked to their working conditions' is supported by the study's title and findings, but the survey is cross-sectional and establishes association rather than causation.
