Tables :: Linking Excel Spreadsheet To Table?

I am creating a database for the company I work for. My boss wants it to have every information possible stored and accessible through the one database. Right now the time sheet that we use is a hard copy that the guys fill out and turn in each week. Before the database started I created an excel sheet for them to start using. My boss wants me to link the excel sheet to a table in access. The way it would work is each of the guys would fill theirs out and email them to me by Friday. I would then link it to the table so that we could easily pull information we needed through a query.

I read online on the office support website that you can link a spreadsheet but then access does not store the data and the data if needed to be changed had to be done through the excel spreadsheet. Doing it like that made it sound to me that each time sheet that was turned in each would would create a new table. I was hoping there was a way to have one table with all the times on it using an employee number as the relationship key. The biggest thing though is that the guys have to use excel to fill out the time sheet because getting each guy access is "not an option" .
