Pretty much everything.
The focus is rarely on the customer, or having a can-do attitude. Good luck providing a lead time or not having to flat out lie to customers because the idiot over scheduling still wants to use a quill and parchment rather than utilizing the ERP software. Even then a "promised date" comes with 25 qualifiers so that nobody has to take responsibility for anything.
Employees have been caught flat out lying and its brushed off or ignored. The numbers are padded and changed, as long as it looks good on a spreadsheet for the owners then everything is good.
The benefits are atrocious. Unless you have worked there forever (which a lot of people have and trust me even though that seems like a good thing at first, it most certainly is not) the PTO is pitiful. Heaven forbid you get sick because there goes any time off to yourself. Moreover, the insurance is expensive and covers some preventative care, but if you want to go to the Dr. expect to miss out on some pay or being dipping into your pitiful PTO.
Oh yeah, back to unethical. If you see a good review on here it's because a pizza party was offered if the scores on here would improve. Way to get your underpaid hungry employees a millisecond of joy! Lies!
I could ramble on and on about the negative that this place offers. My best advice if you are looking at a position here: move along. Don't waste your time having your happiness depleted and your soul crushed by working here. There are plenty of upstanding companies where employees are valued.
