Most people like to rest after a day's hard work but he seemed to have an inexhaustive supply of energy.
Is the above sentence grammatically correct ? Is the phrase day's hard work correct or is it hard day's work ?
Both options are grammatically correct. However, you should probably use a hard day's work instead of a day's hard work.
A hard day's work is a set phrase, even though "hard" is modifying "day." A day's hard work is actually more logical -- "hard work" is a very common phrase. However, native English speakers would not usually say a day's hard work. It sounds awkward, because a hard day's work is much more common -- and to change the order of the words seems like a humorous attempt to misquote the set phrase on purpose.
So I would recommend using hard day's work.
A perfectly good alternative is to say a day of hard work. Or even a long day of back-breaking work.
