[Grammar] Is the word "work' considered as a countable or uncountable noun?

Hello

Is the word "work' considered as a countable or uncountable noun?

For example, which one of the following sentences are correct?

1) I have an urgent work.

2) I have urgent work.

Thanks

In this context, it's uncountable, so it's "I have [some] urgent work [to do]".

However, "work" can be a countable noun. For example, "the works of Shakespeare".
