Uber are a typical 'race to the bottom' company.
They make billions but pay virtually no tax. They pay their drivers a pittance with a very poor record on holiday and sickness pay.
Little wonder they have so many oddballs working for them.
The drivers are all self employed and pay a commission for the work they receive...
Last time I looked, self employed people don't get paid holidays or sick pay... actually, sick pay is rare comodity anywhere in the real world.
When I was a lorryist I was a self employed agency worker and it was great. I could work as much or as little as I liked and all they asked was that I let them know my availability a week in advance. This allowed me to get on with other self employed ventures with the security of a fall back plan!
Of course I didn't get holiday or sick pay, nor was there any pension provision, but I went into it with my eyes wide open!
On the flip side, I once worked as a self employed Sales Rep, which turned out to be a nightmare when they expected me to work 24/7!
I quit after 2 weeks when I told them I needed a day off and they said I couldn't have one. I told them to Go Forth!
and then had to battle them for the money they owed me, which nearly ended up in court.
