Hello,

What punctuation to use with this long sentence?

A good employee aspiring prefection, and exerting renless efforts, and being honest to ones' self - deserves to be promoted.

I used a dash here, but I'm not sure if this is right?

Any help?

The dash would be incorrect among other errors e.g. spelling: "renless" and incorrect use of the apostrophe.

Whoops! Sorry, I was in a hurry.
Here is the correct sentence.

A good employee aspiring prefection, and exerting restless efforts, and being honest to one's self - deserves to be promoted.

What should I use instead of the dash?

Thanks.

A good employee aspiring to perfection, [STRIKE]and[/STRIKE] [STRIKE]exerting[/STRIKE] making [STRIKE]rest[/STRIKE] tireless efforts and being honest to [STRIKE]one's[/STRIKE] himself deserves to be promoted.

That's just about possible. You cannot put one dash between a subject and its verb.

It's more natural this way:

Good employees who aspire to perfection, who make tireless efforts(,) and who are honest to themselves deserve promotion.

I see, thank you.
Let me give you a better example.

If you read the text book, read extra stuff online, do assignments on time, and turn the research on time, you will get a good grade.

Is the comma appropriate before "you will get a good grade"?
Won't a semi colon be better to help distinguish this part from the rest of the clutter which is full of commas?

Thanks.

If you start with the main clause, and combine the two 'on time' clauses it perhaps reads better -

You will get a good grade if you read the text book, read extra stuff online, and do assignments and turn in the research on time
