description <!--HTML-->CP violation in B<sup>0</sup> and B<sup>+</sup> decays has already been extensively investigated at the B-factories over the last years, while the corresponding knowlege in the B<sup>0</sup><sub>s</sub> system has been lacking so far. B<sup>0</sup><sub>s</sub> mesons are produced with large cross section at the Tevatron collider. Following the measurement of the B<sup>0</sup><sub>s</sub> to <font style="text-decoration: overline;">B</font><sup>0</sup><sub>s</sub> oscillation frequency in 2006, the D∅ and CDF experiments have now investigated CP asymmetries in B<sup>0</sup><sub>s</sub> meson decays. We report on the first flavor-tagged analyses from both experiments using B<sup>0</sup><sub>s</sub> decays to J/ψφ. This channel is sensitive not only to the width difference ΔΓ in the B<sup>0</sup><sub>s</sub> system but also to the (CP violating) weak phase β<sub>s</sub>.
