The last time I saw a Ceridian payroll system it was fucking broken. Their web interface was written in ASP VBScript and looked it. It was so stunningly well-coded that if you closed the browser window without explicitly clicking the "Log off" button, it will count you as still logged in but lose critical state, meaning you couldn't get back onto your timesheet without calling someone down from HR who knew the voodoo chicken dance it took to get Ceridian unwedged.

I hope they've improved since then. Otherwise this person is in for a bit of a hassle.
