There is no control over the fast pace of work. Cold temperatures add to the risks. The noise is overwhelming. Going to the bathroom requires permission. Un excused absence from the line is grounds for dismissal.
Employers define it as a voluntary quit.
For some it is easier to pee in their pants. There is just no time, except during the short breaks when the bathrooms are crowded. Soap dispensers are usually empty, toilets overflow, and drains are clogged with cigarette butts. The line is often so fast paced that it looks like chaos. Arms, boxes, and poultry fly in every direction.
