Laravel worktable user specific not working

I am trying to build an web application where an employee can review his working times. This works until now, showing you a list of all employees and their workshifts.

This is nice and all, but we would like to have to have that only available to the admins. The regular Employees should only have access to their personal records.

I personally am running out of options considering you cannot place an if inside the foreach loop. So please let me know if it is possible to do something in the context of:

IF Auth::user()->admin == 1{

//Show all employee records

} ELSE

//Show only logged in employee's record

I highly advice you look at the example as to get a better idea of what I am trying to build.
