My original response was in support of someone else stating they had to wait for their computer to boot up before they log in. Getting there 10 minutes earlier still means you're at the office not getting paid.
In my opinion, if the employee has to use their computer as a timeclock, and said timeclock takes 10 minutes to boot up, they should be paid for those 10 minutes.
It's the same thing as having to wait around to get your bag checked. If your waiting on something (equipment, or someone to security check you), you should be paid.
Edit: And I apologize for any confusion. I assumed that you had read the preceding posts regarding my rant!
Thank you very much, I honestly appreciate your response.
