I took 6 vacation in a row starting 1-14-2017, 1-21-2017, 1-28-2017, 2-4-2017,2-11-2017---UPS put these checks ending in year 2016. They were sent with my last check in December 2016 in which they pay you 2 weeks ahead of time. I didn't want those 6 vacation checks paid in 2016. It affects year to date pay, hours, federal taxes,401k and pension hours earned. UPS took 6 vacation checks and said they would void and reissue those checks but I don't know how they are going fix your end totals with my last check of the year in 2016.
