Union chiefs have warned that Glasgow taxi drivers and private hire drivers are now working under extreme pressure since the introduction of firms such as Uber, and are failing to seek help for mental stress caused from having to work excessive hours to cover the cost of living. It has been claimed that drivers are now having to work up to 70 hours a week to earn a living wage by Union secretary Steven Grant as reported in the Evening Times . It's claimed that there is now a massive over supply of drivers within the private hire sector since the rise of ride-hailing app Uber, and there is simply not enough work to go around. Drivers having to work 10 hours a day 7 days a week are refusing to see their GP to discuss mental health issues caused from work related pressure because they fear having their licence revoked, it has been suggested. Glasgow City Council have confirmed that they will be looking into capping the amount of private hire drivers in the city but first they must receive guidance from the Scottish government. Glasgow is not the only city that has seen a significant rise in the number of private hire licences being issued, London is also dealing with a huge number of new drivers joining firms such as Uber on a weekly basis. What city do you operate in? Do you think it's important to cap the number of licenses being issued? Let us know in the comments below.
