Personally, I believe that both of these new French laws are positive measures to correct some long-standing problems of the society, irrespective of their effectiveness after implementation.

The poposed ban on smartphones at school will prevent students from a constant distraction, or even reduce the risk of addiction from the early stage of life. More often than not, teachers have to pause to intervene in students' use of digital devices in the middle of the class, causing tension between teachers and students. Although I can foresee that students may feel resented when this law is in effect in the beginning, they might change their perspectives when looking back on it in the future. On top of that, it's likely that this law will reduce peer pressure when smartphones aren't allowed in classroom, which in turn will help low-income students better fit into a social life at school.   

As far as work-related emails after work are concerned, I do agree that extra work should be avoided; however,  depending on the scope of work of an individual and the industry he/she belongs to, extra work is still inevitable if you want to keep your job. In Asia, for example, if your work involves transactions across different time zones, you can either choose to be on duty late at night to please your clients, or let them go. If the same law were to be implemented here, I don't think it would make any effect on any industry, unless you're indispensable in some way. 

Despite the fact that I don't know the first thing about the situations in French schools and workplace, I am hoping that these laws will pave the way for the better future in France. :)

I suppose your translation works in the written form. However, if you'd like to put it in a heading of a formal letter or on a business card, I'd prefer to revise it as the following order,  

Headquarter / Head Office of xxx International recruitment agency, Japan. 

I don't suggest that you emphasize on temporary employment because that will inevitably restrict your scope of work, wouldn't it be better to cater to a wider range of clients, for both long-term and temporary employments even if you would only target on a specifc area? 

Welcoming the weekend...

Well written! I made some corrections to make your sentences flow better and natural for your reference. That being said, your grammatical mistakes are so minor that they won't affect reader's understanding of your diary. Another thing is that if you want to sound more colloquial, you can say 我的妻子吃素 rather than a 素食主义者. Glad to hear that you enjoyed Sichuan and Xinjiang cuisines.

Although there're already a variety of materials that teach English pronunciation out there, none of the materials will refine your pronunciation in conversation. Only the basics of relationship between vowels and syllables, common vocabulary and sound linking will be taught. Therefore, I believe the best way to improve pronunciation is to practice reading texts or transcripts as fast as you can, and then upload your recording for native speakers to correct. Hope it helps.
