I arrive on time on a daily basis.
We actually have 7 minute window in which we are to punch in at. We aren't too punch in earlier than 7 minutes prior to the top of the hour.....company has to pay us for a quarter hour if we do; so we are not to punch in early.
We have that same 7 minute window to punch out of past the top of the hour. If we punch out past that, company has to pay for a quarter hour of work time. They do NOT want to do that on a consistent basis.
