I keep track of my hours very carefully. I even take pics of the computer screen (my shop steward told me to do this, so spare me the "no pics in ups" stuff) when I punch out each day. The start times listed are usually wrong. For example, start time is 4:15 (I punch in at 4:13) but the start time listed in the system is 4:50 or something. This is common. Usually it's corrected without incident by the supervisors at the end of each week. But the last two weeks, they have not corrected the times for me, thus not paying me for the time I actually worked and have documented proof that I worked. I did print out the correct times and hours totals for each day and gave the documents to my supervisor. They had that documentation *last Tuesday*, but in today's paystub online, the missing time was not added to this week's paycheck. Should I keep waiting? Should I give them another round of copies of the documentation and assume they just forgot? Is there a penalty for not correcting the hours and paying me by the first paycheck following notification of the mistake? Thanks.
