Cuca: Talk about a thankless job.

库卡：那可真是个吃力不讨好的工作。

Although I was fully aware that it was a thankless job, I had to do it.

明知讨不到好儿，也得去干。

A new study says that, income notwithstanding, having a demanding, unstable and thankless job may make you even unhappier than not having a job at all.

一项新的研究称，尽管收入是一项必需的要求，但是不稳定的不能获得成就感的工作或许比没有工作使你更不快乐。
