....does it mean they can give you 24 hours notice on any day off that you will be working instead of having a day off?
In a nutshell and roughly speaking -yes. It is part and parcel of the bidline system - the justification for it goes along the lines that "if you, the pilots want a preference bidding system/Bidline then we, the company, need an emergency mechanism to catering for uncovered work." Now according to the rule set it's meant to be a "random and infrequent" process, and it used to be so - uncovered work was generally picked up pilots bidding for overtime or by those on Reserve & standby. Problem is that recently for some (mainly but not exclusively the short haul P2s) it has become anything but "random and infrequent".....as reasons for
that happening..
