How is this even possible? If a security guard earns $25,000 per year then they are earning about $12 per hour ($25,000 / (40 hours * 52 weeks).
At 1.5 times their base rate -- the overtime rate would be $18 per hour.
$931,000 / 3 years = $310,333 per year.
$310,333 / $18 per hours = means that they worked 17,240 hours of overtime in the year.
The number of hours in the year is 8,760 (24 hours per day * 365 days)
The number of possible hours devoted to overtime for this security worker is 8,760 - 2080 (52 weeks * 8 hours) = 6,680 possible overtime hours to work in the year (without sleep, etc.)
Yet the overtime claim shows the security guard worked 17,240 overtime hours each year.
Something does not add up.
