Employee closes up shop after coworker doesn't show up, gets reprimanded by HR for not covering their shift: 'Trying to suppress laughter at the idea I might work an unplanned double-shift'

Showing up is 99% of the job. In most cases, you can't do your job if you're not there. That's why employers love people who can be on time. If you can arrive on time reliably, then you're halfway to being the most employable person out there. For a lot of jobs, it's really that simple.
