Say Again ...
Getting woken at 0300 if you're on s/by happens at any airline ! I've never worked anywhere in the last 21 years where this isn't a factor ! If you weren't on s/by though then you certainly have a valid point.
I can't comment on previous practices at Emerald for crew callouts or lack of crew in general, but I do know Ops & Crewing are (or about to) go through a radical shake-up and bring them into the 21st century giving them the tools and people to do the job more efficiently.
The ops/crewing dept has been 'neglected' for want of a better word for years, not intentionally, but for a myriad of reasons. This has now been recognised by senior mngt, and is being addressed.
This will hopefully make their lives easier, and the net result make the FD crews lives easier as well.
