Find Corresponding Date Range Based On Single Date And ID Number

I'm trying to combine the hours that a employee worked on a single date, with one of multiple time periods that exist for that employee.

I have two sets of data.
Set 1 (hours)
Employee number, date, hours
12345, 1-2-2014, 6
12345, 1-3-2014, 8
12345, 1-10-2014, 8

Set 2 (periods)
Employee number, start date, end date
12345, 1-1-2014, 4-1-2014
12345, 6-1-2014, 1-2-2014

What I'd like to do is to add the start and end date of Set 2 to Set 1 for every row in Set 1

In above example the result should be like this.
12345, 1-2-2014, 6, 1-1-2014, 4-1-2014
12345, 1-2-2014, 8, 1-1-2014, 4-1-2014
12345, 1-10-2014, 8, 6-1-2014, 1-2-2014
