Why fix the road in oxford is inefficiency?
I asked this question because of I noticed the road which is London road , it started to fix from last
year maybe June, but still haven's finish.
I think this because of some reason which are :
1. Because of the weather of Oxford ischangeable,workers can not do something when the weather
is rainy. That's means the weather effect the efficiency.
2. Because of the weather too, they must have some special resources to fix the road, like some
stone can avoid the rainy. But it need a long time to make sure the quantity of the road.
3. The wage for the workers are high, because of there are narrow range of people can do this job,
it need aprofessional skills , there aren't a lot of people can do that, so the government may spend
more and recruit people ,but just a few. Because they do not have a lot of people to do that, how
can improve efficiency on it?
4. Also because it is a main road in Oxford, so the traffic is busy, it must effect the efficiency.
