For this specific case, David Carlisle's answer works great. But, in general if you want table to span the entire \linewidth, I find using the X column from tabularx to be very useful:

Notes:
The showframe package was used just to show the page margins. It is not needed in your actual use case. was just to show the page margins.
Here I have used the X column to be the blank column between the two groups of text. Hence the double && separating the two groups.
The @{} at the left and right of the table remove the inter column padding that would normally be applied.
Code:
\documentclass{article} \usepackage{tabularx} \usepackage{showframe} \begin{document} \noindent \begin{tabularx}{\linewidth}{@{}l l X l l@{}} Name: & XX && Email: & [email protected]\\ Work: & YYY && Phone: & +1 666222\\ \end{tabularx}% \end{document}
