I realize how dramatic that sounds, but bear with me here.
Think about any workplace you’ve ever worked in during the holidays. Employees, even customers, are not nearly as focused on the work-at-hand as they are during non-holiday times. They may be taking sick days or personal days off (shopping and baking take precedence!), they may be leaving work early to see their kids in the Holiday Concert at school. They may be laughing and joking about how someone behaved at the office party the night before, or maybe they are distracted by thoughts of the shopping that isn’t yet done, or the in-laws (who they never really get along with) who are arriving tomorrow.
And that’s the point. There are dozens of time and thought-consuming distractions during holiday times. Then, as the holiday date draws closer, the most senior staff members (if not everyone) begin checking out for days or weeks of vacation time. Important questions go on a shelf until those folks return to work. Less senior staff, or part-timers, are the ones left to make snap decisions when called for, no matter how dire those decisions are. They make them to the best of their ability, but there’s always a question about whether they are making the right decision.
