Clocking inWhat it means, in plain English

Clocking in is the act of recording the time you start work, with clocking out marking the end of the shift or break. The resulting punch data drives timesheets, overtime calculations and lateness reporting. UK employers should be clear in policy about whether paid time starts at the punch or at the rostered shift start, as rounding rules that consistently favour the employer risk underpaying staff below the National Minimum Wage.
