Yes, you do need to clock out for a double shift. Once your first shift ends, clock-out, and then clock-in to your second shift.

This is especially important because not all shifts have the same rate of pay.

If you neglect to clock into the second shift, the app will recognize it as a No Call No Show, however, the ESHYFT team will be able to see that it is a double and will not penalize it.
