My father in-law is a mail carrier for USPS and he complains so much about x-mas time its funny to hear him complain hes been doing it for 35yrs and is retiring this year so hes counting the days till he doesn't have to work the holidays anymore. I guess they are ridiculous
hours per week. Peak volume of mail for the year and the post office management doesn't want to hire more people so the regulars work their asses off from about Nov 1 through the first or second week in January.
