Actually, you work for two versions of a company that has Dissociative Identity Disorder, often changing character from month to month.
For example, you may take 10 days holidays in January and find that in the remaining 21 working days you will have 85 hours credit. In other words, your employer has blithely stolen from you and your family any opportunity to use your vacation to recover physically.
Now suppose you found that January's arrangement actually worked for you, so for March you ask for all your duties to be compressed into 21 days, leaving 10 days of freedom for yourself. D.I.D. kicks in and your employer claims they could never countenance such an arrangement, that would be a compressed roster and in their eyes it would be manifestly unsafe.
Unhinged and beyond parody.
