There is an issue with this program: it omits the first row.

It's better to use enumerate, e.g.:

for n, row in enumerate(matrix): ...


To make the change you need, use list comprehension to make sums of all
rows, sort it (using list sort method); iterate over it using
enumerate() and print out "employee N, sum of hours:"
