Run 2 of the LHC ended in 2018. Currently the experimentalists are busy analyzing that data, and the theoreticians are busy improving the theoretical prediction precision to the level of the experiment. If we had no new data, it would take a decade for this work to be finished.

Run 3 of the LHC is scheduled for 2021-2023. After that the High Luminosity LHC upgrade will take place, with data taking currently scheduled for 2026-2038 [1].

Overall, just with the LHC-related projects in the foreseeable future we are looking at decades worth of measurement and research. There's no reason to worry about the lack of work to do :)
