Avantages
EnerSys offers good benefits, as well as decent starting PTO. Some good coworkers to work along with. The corporate cafeteria is pretty good also. At best, use EnerSys as an experience builder to get a better job somewhere else.
Inconvénients
The leadership and management in corporate is as toxic as it can get. Incompetent people are promoted to positions of power they have no business being in. The pay isn't competitive, and the workload will be piled up until your performance suffers. These managers idolize and aspire for a "Wolf of Wall Street" type of office, and will actively target anyone whom they don't personally like. The turnover in my department was ridiculous. HR isn't there to help, only to try to protect the company from potential lawsuits. Employees who use their PTO are discussed negatively by upper management behind their backs. At least one manager will loudly berate his employees in front of other employees, as well as discuss loudly over the phone with other managers performance of other employees. I've personally seen that manager try to use spelling errors in emails sent to supervisors of employees he didn't like, in attempt to get them terminated.
