rubik,
The "2-3 months chaos" is the 4 weeks random roster period after every 16 weeks 5254.
I worked 5254 for a while and (for me) it gave better quality of life, both during the working days, and the days off.
I don't mind losing a block of leave, since I get it back spread over the year.
I do mind not being able to plan my life for 4 weeks in 20, so this for me is the "price".
Given my exhaustion doing a shift change each and every week, I am willing to pay this price.
The amount of work I'll actually do each year will of course stay the same - namely 830 (ish) hours a year.
How anyone can get so upset with this change, I just cannot begin to understand.
