Pros

Good learning opportunity to grow when starting out. Decent opportunity for overtime depending on the department.

Cons

Terrible work life balance starting out. A lot of drafting (forced overtime) depending on the department. Quality of management varies drastically from department to department.

Pros

Good yearly bonus and benefits Potential for flexibility? If you have a doctor's appointment and you need to leave, you won't be guiltied I guess. Those workers who are good, are extremely valuable but they are 1 and few in between

Cons

1. They hire from within which is good however, the standards are significantly lowered especially with higher management. They hire people, who have no experience in manufacturing, lead a manufacturing department where they make irrational decisions and lean on lower reports to make their decisions for them. They also have a higher than thou attitude where they leave early but leave their teams manufacturing into the evening 2. You, as a lower report, have to wait a year to move into a different position but then shuffle associate directors and above to different departments in less than a year (hypocritical) 3. If you're an ancillary group supporting manufacturing, they're treated like service staff 4. Higher management dont push their reports to learn new systems/new processes that the company itself forces but expect supporting groups to do the work for their group 5. You're forced to work shifts that are not in your job description or be on call at best. The company makes record profits but can't afford to hire people to work those specified shifts, what a joke 6. The contractors do and know more than the full time employees sometimes but then won't get converted which is insane 7. Those who actually do their job to their full capacity (and most of the time more) get burdened with picking up the slack of the 10 or so folks who disappear at all times of the day to the point where management has to chase them down 8. This building houses 3 departments but it almost feels like it's a sibling dynamic, the department that throws a tantrum louder gets the attention of the parent ie higher management such as extra support and extra funding 9. I mentioned there is potential to wfh some days but if you're busy picking up the slack of people, you basically cant 10. Good PTO days but if your team is abusing those days and taking off, you're forced to stay on in order to ensure the project they should be taking care of moves forward
