After reading an article, ，I wrote a summary.

A report said that their average rest days are 9 daysy take an average of 9 vacation days per year, even though their employer gaveallows them 20days to rest every year.

It’s said that law makers proposed some new laws in this report.

But, people don’t like to take these vacations Bbecause they want to work harder and harder to get more money.

Because they will always want to earn more money than others so they will always work hard.

This sentence can be combined with the previous sentence.

Even if the lawmakers told them to rest.

This sentence can be further connected to the previous sentence with a comma. Overall, it would look like "In my opinion, the way people think about work will not change in a few years because they will always want to earn more money than others, even if the law makers told them to rest.

After reading an article ，I wrote a summaryI wrote a summary on an article that I had read.

The original is understandable but this reads better as the subject of the writing is the summary itself

Many Japanese workers only have rest intake a holiday for a few days every year.

Normally a holiday refers to an actual trip somewhere, but when talking about work it can mean any kind of break from work (in the UK we say holiday, in US English this would probably be vacation time too)

A report said that their average rest days aredays taken was 9 days even though their employers gaive them 20 days to restholiday every year.

This might be hard to understand but days taken is past tense but the allowance always exists and so doesn't have to be

It’s said that lawmakers proposed some new laws in this reportto change this.

The report is already the subject so don't need to mention it again.

But people don’t like to take these vacations Bbecause they want to work harder and harder to get more money.

In my opinion, the way people think about work will not change in a few yearsfor some time.

Since this is your opinion, specifying "a few years" sounds unnatural (unless you knew the exact date in the future). Something like "for some time" or "for many years" sounds better.
