Roster for Gateline Staff

Looking at job based at Woking, believe shifts are 6am to 2pm and 2pm to 10pm. How does this normally work? IE. 2 early, 2 late, 2 off. Week early, week late, week off.

Thanks

Been a while since I did it, but it worked out as a 5 day weekend every 4 weeks. Mainly single days off elsewhere in the roster. Maximum of 8 days worked in a row. Sundays were 0930-1730, every other day 0600-1400 or 1400-2200. Some shifts were 'spare', roughly 1 week in 4, where you could be rostered either early or late, and at other stations in the area.
