My work schedule is anything but consistent during certain points of the year (like right now). I try to be flexible and ride when I can. If there isn't time for a ride and I need to do something then I go out for a run. I have a gym membership so there is always spin classes or swimming, etc... But if I work long hours one day I schedule my work week to have a shorter day and I will use that time to ride. I might shift my work hours to the evening at least once a week so that would give me a morning for a longer ride.
