We have a new staff member at our sushi bar .

I am supposed to teach him because I was the new one before he started working.

and is very slow, but I can't tell him to do somethings more quickly since I was not good at the first time either, and he's older than I am. [You could also say "I can't tell him to hurry up," which would be a little less polite but more natural-sounding. You can use either "at first" or "the first time," though not both; "the first time" implies just the very first time you did it, while "at first" conveys a longer period of time. Finally, when you're making comparisons, I corrected "than me" to "than I," which is grammatically correct, but a lot of native speakers also make this mistake.]

I found it hard to teach someone who is older than me and who seems doesn't seem to have any passion for his job.

Today I cleaned up our shop with him and to me, it seemed like such a disaster to me.

Maybe he didn't realize that he was doing everything so slowly.

I had to do extra things he hadn't even started to before he remembered about them.

but what I am really worried about is about my boss.

All the rest of us can guess that he doesn't like the new staff member for some reason, and he wants me to teach the new person.

So if he makes any mistakes, I will get something like a hard time about it.

I just wish he'd work with more enthusiasm...

A new co-worker A new employee

We have a new employee at our sushi bar.

I should teach him, because I was the new one before he came.

He is not really good at this work,

and he is very slow; but, I couldn't tell him to do something more quickl.y I was not good the first time as well and he's older than me.

Today, I cleaned up our shop with him and it was such a disaster.

Maybe, he didn't think that he did everything so slow.

I had to do extra things, that he didn't start, before he recalled them.

That wasn't a problem

, but what I really worry about is my boss.

Why he doesn't like the new employee, all of us can guess. He wanted me to teach the new employee.

It means if he made any mistakes, our boss would give me a 'hardtime.'

I just wish he'd do his work more eagerly.
