These proceedings present the current status of measurements of the CP-violating phase $\phi_s$ by the LHCb collaboration, reviewing the measurements in channels such as $B_s^0\to J/\psi\phi$, $B_s^0\to J/\psi\pi^+\pi^-$ and $B_s^0\to\psi(2S)\phi$. The observation of the $B_s^0\to\eta_c\phi$ decay mode is presented for the first time, which can be used to measure \phis\ with larger data samples that will be collected over the coming years by the LHCb experiment. Finally, the expected increase in precision from LHCb measurements of $\phi_s$ over the next decade is presented.
