(Bloomberg) -- Taxi drivers in Madrid will go on strike this month to insist on more regulations for ride-sharing car services such as Uber, ABC reports, citing union leaders.

Driver will stop working on Jan. 21, two days before Madrid hosts an international tourism fair. Some unions are still deciding whether to join the strike and will hold votes Tuesday and Wednesday, ABC reports.

In July, taxi drivers in Barcelona and Madrid blockaded highways in an attempt to block the award of new licences to companies such as Uber Technologies Inc. and Maxi Mobility Spain SL’s Cabify.
