I suspect that the RNG caught you in it's relentless steel jaws... There's two tricks I use. I usually have two sales managers (so my production manager can do research when she's not dealing with production tasks), so you have a better chance of getting jobs. (And don't forget to upgrade in the research panel!) I also have a goodly stable of idols (9-12), because more idols means more jobs (spread out so as not to kill their stamina).
