Every area has exactly the compliment of employees needed for minimum function. No more, no less. Which means you better not get sick nor be late, lest your coworkers despise you for making their already chaotic day, a complete misery.
This makes for an impossible scenario of completing everything in an error free, timely manner.
Clearly management has no understanding how to fully tap its onboard work resource potential. While some folks are working 6 hours and out, your struggling to make everything fit neatly into an extremely company budgeted 8 hours. This working model makes for a high stress, overworked mentality that's doomed to battle an unnecessary turnover rate.
