We all swipe in with time cards.  It used to be an honor system, but of
course then you have the occasional employee who will take advantage of a
lax system.  I f a tech was consistently late - even by a few minutes, but
often, I would address it with them, explaining that they need to be at
their work station at the designanted time.  If it continued I would report
it to the lab director and be sure it was addressed during the employee's
evaluation.  We don't worry about lateness due to weather, traffic, car
problems, etc.  One thing to keep in mind about swipe-in systems:  With our
kronos system if you swipe in at 6:05, you are counted as being there at
6:00.  If you swipe in at (I believe) 6:07 you are counted as having
checked in at 6:15.  It rounds to the quarter hour.  The people who are
prone to fudging may actually wait around at the end of the shift for that
extra minute to tick by so they get an extra 15 minutes on their time card.
