Job I started about 8 months ago runs a compressed schedule, eight 9's and an 8. We do the 8 hour day one Friday, get the following Friday off. Start work at 6AM, get 45 minute lunch, get off at 3:45PM.
That first month or so was a
killer for me. Pretty much an ambulatory zombie-esque person until the end of January. Now I'm so used to getting up at 4:30AM for work, that "sleeping in" on the weekends means staying in bed until 5:30!!
What's funny is that my cat got used to the schedule too, so every morning he's waking me up right around the time the clock radio starts playing music, and every night at 9, he's nagging me to get ready for bed. Not exactly the type of nagging pussy I wanted in life!!
