Pros
The cons overwhelm the pros so nothing to add here.
Cons
Managers do their best to squeeze the blood and sweat out of every single employee. It is next to impossible to get vacation. Work hours extend to nights regularly, most weekends, and most holidays. Managers use you as a slave resource and have no respect for your personal time. This is not limited to few managers but a company-wide culture. There is zero learning to advance your career. You are expected to do your job without asking any questions. Whatever you are able to figure out, it applies only to the company’s antiquated, proprietary process that is not found anywhere else. Senior managers are not knowledgeable and play lots of politics at the expense of employees. They will never give credit for your good work but focus on projecting everything good as their own idea but everything bad as the fault of lower employees. Parallon is all about getting more out of employees for less. HR is there to protect the company. Run instead of walk away if you’re even thinking about applying for a position in this company.
