You have to understand what an extra board is. You are on the board for weeks at a time. You get called 90 minutes before your start time. You then work 12 hours and the minute you clock out you are allowed 10 hours rest. They will most likely call you 10 hours and 1 minute later. You can do this 6 times in a row before a mandatory 24 hour rest.
So let’s just break it down:
Sunday: Called at 01:00 for 03:00. Work until 15:00
Monday: called at 13:00 for 15:00. Work until midnight
Tuesday: wait all day for a call because lineup says next train is at noon. Actually get called at 23:00. Work from 01:00 Wed until 13:00 Wed.
Wednesday: try and adjust to your now
ed circadian rhythm. You went to bed at 14:00 and are legally rested at midnight. Also you waited more than 12 hours on Tuesday so you got your own reset.
Thurs: Called at 00:01 for 02:01
Keep going with no days off at all. No sick days allowed either unless you accumulated them or vacation time which is usually after five years. That’s what they’re striking about
