365x24x7

Mon Apr 18 12:59:21 UTC 2011

My guys work 12 hour shifts.  2 days on, 2 days off, 3 days on, 2 days off, 2 on 3 off.  The three days on is always friday-sunday so every other weekend they either have a 3 day weekend or 3 days of work.

In a pay period, with 30 minute lunch per shift it comes to 80.5 hours.  I keep my guys on the same shifts for consistancy.

	"People who change shifts every few days are going to have all
	kinds of problems related to memory and learning, Fishbein said.
	This kind of schedule especially affects what he called
	relational memories, which involve the ability to understand
	how one thing is related to another.

	"Controllers are often scheduled for a week of midnight shifts 
	followed by a week of morning shifts and then a week on swing
	shifts. This pattern, sleep scientists say, interrupts the body's
	natural sleep cycles."
