I've just put in 14 hours, and I'm sure glad they're over!
During the first two or three years of working here, we all used to put in 10- to 14-hour days during basketball and baseball, and work six or seven days a week all the time, until someone finally gave in and started letting the salaried folks have an extra day off during the week. Right nice of 'em.
So, over time, I've grown accustomed to working shorter (read "normal"), 8-hour days.
There are a couple salaried workers, though, who still have to put in the rough hours during baseball season, due to the nature of their jobs. I can totally sympathize, but I'm glad I get to go home in summer before the sun sets!
