Peris: I choose to work about a 10 hour day but could easily work your standard 8 hour day and have managed my same schedule in "crunch" situations. I've basically kept that same schedule throughout my entire career excluding a few "crazy" situations and my first job which had me working 12 - 16 hours more often than not.
I remember at my first job during Alpha we worked 12+ hour days for 19 days straight. Not 19 work days straight, 19 literal days straight (Monday to Sunday). Some people worked 16+ for those 19 days straight. It seems usually when crunch hours like that are put on people it's because of bad scheduling which is funny…
