"Given this, they should be able to adjust the staffing accordingly...". That right there is the hardest problem to solve. People are fickle, especially ones who work as security guards (or TSA agents, very similar duties). It's a low paying job that is boring as fuck. It's very difficult to find people willing to sit in a chair or stand in uniform for 8-12 hours a day. Not only that, but there is no incentive to do good work as a security guard; you might get lucky and get promoted to supervisor? Maybe? There aren't a lot of positions in security beyond the uniform. So they can't just "adjust the staffing". Where are these staff going to come from, thin air? If a staff member already worked 40 hours this week, I can't ask him to do another shift, lest I pay overtime and blow the budget. If two of my employees call in sick, I can't just call up my night shift employees to fill the shift, otherwise they won't be able to work the night shift. And I need to give my staff stable hours - I can't ask someone to work a night shift, then 2 days later, work the morning shift, then the afternoon, etc. And to top it all off, I need to give my employees their work schedule a week in advance (at least) so they can plan their lives around it. TL;DR, staffing is hard
