I hate a meetings.

Japanese workers like to have a lot of meetings to make a decision because a consensus is the most important thing to have at work.

There are a few reasons why they like a meetings.

If you get a consensus, it is easy to pass the buck to someone else.

Anyway, whatever the reasons are, they tend to hold a meetings for a meeting because nobody can make a decision or give a straight opinion.

They also need a pre-meeting to lay the groundwork for the decisions.

I’m sure that most of meetings are wastes of time.

Uni-clothing company announced that they only use English during their meetings in order to globalize the company.

I heard that the company at which I work at made the same rule, but sooner or later the rule disappeared.

there are some advantages to using English.

First, as you know, Japanese workers are not good at speaking English, therefore they don’t talk about unnecessary things and it shortens meetings.

Second, they don’t use connotations or speak vaguely in English and it would make their point clear.

Unfortunately nobody suggests using English during the meetings in my office.

‘Cause the meeting must be their best time to relax.

I’m sure that most of meetings are wasting time. (I think this is fine as it is. Wasting is an accurate verb, and "a waste of time" is more of a colloquial phrase. You could say "wasting my time" or "wasting our time")

Uni-clothing company announced that they use only English during their meetings in order to globalize the company. (I like the way you wrote this better than the correction given. If you say they "only use English during their meetings" it could mean that they never use English any other time, rather than meaning that they don't speak Japanese at all during the meeting.)
