Multiple は particles in sentences from IAIJ and NHK web easy


I came across this sentence in IAIJ (the context was an adult studying
japanese on an elementary schoolbook, saying that there are a lot of simple
readings but also more interesting ones providing cultural education that,
however, where in contrast with his own sense of education):

> ほかに修身の読本もあって、‘’サイタサイタサクラガサイタ”に比べれば多少面白かったが、その道徳観は私の **それ** と **は**
> 大いに矛盾していた。

My translation is the following:

> Apart from that, there were also cultural education readings that, compared
> with "Saita saita sakura ga saita" where quite interesting but, that view of
> education greatly contradicted mine.

To my knowledge「XはYと矛盾する」means " _X contradicts Y_ " so I don't understand
what is purpose of the それ and は (highlighted in bold in the sentence) there.
Isn't the following correct (I just removed them from the sentence)?

> ほかに修身の読本もあって、‘’サイタサイタサクラガサイタ”に比べれば多少面白かったが、その道徳観は私のと大いに矛盾していた。

The same kind of problem appears also in this sentence (taken from NHK web
easy):

> 法律 **では** 、会社は、働く人に仕事を休むように言った場合、働く人にお金を払わなければなりません。

Why not simply:

> 法律 **で** 、会社は、働く人に仕事を休むように言った場合、働く人にお金を払わなければなりません。

What am I missing?




修身 is an old word for "moral class/education", and 道徳観 is "ethical view" or
"idea of morality". 私のそれ is "that of myself", i.e., "my own 道徳観". 私のそれ is
interchangeable with 私の here; it's jut two ways of saying "mine". は after
私のそれと is optional, and I think it can be understood simply as a contrastive-
wa. その道徳観は私のと大いに矛盾していた equally makes sense.

> Besides, there was also a moral reading-book, which was somewhat more
> interesting as compared with "Saita saita sakura ga saita", but the idea of
> morality in the book was very contradictory to that of myself.

(You can read a 修身 textbook here: <http://doi.org/10.11501/1275558>)

As for the last sentence, [this
question](https://japanese.stackexchange.com/q/5375/5010) is related. (I
personally tend to think this is a "double-topic" sentence, although it may
not be how it is usually explained in JSL textbooks... Personally I can hardly
feel a contrastive nuance in a sentence like 今日は学校は休みです.)
