Rampant nepotism within the company. Favored staff can behave with impunity and any complaints regarding safety, company protocol, or even harsh treatment and insulting begets no action. You'll be pulled aside to receive a pep talk, so the status quo can continue.
Serious concerns regarding adherence to safety and maintenance protocols are dismissed. I worried that one day I'd be bystander to a serious mishap. Lacking any semblance of practical safety behaviors throughout culture. Management prioritizes high manning utilization over safety.
Poor communication, planning, and over scheduling. Stress of being sent to an unfamiliar site, to work or program an unfamiliar system after being pulled off scheduled work, simply to fill their planning oversights.
Mgmt often makes promises and verbal guarantees knowing they won't follow through. Manning, training opportunities, saying people will receive work trucks then when they become available refusing to provide them. Sending people to emergency travel, overnight shifts, and not paying pier diem, shift differential or other industry standard pay practice.
They'll say certain integrations are possible, only later to find they just didn't want the cost to implement. Which is a valid choice for operations, but no need to mislead staff about why something won't happen or tell them it's inbound. In general, many are bad faith actors, saying whatever necessary to keep people striving, yet turnover is still ATROCIOUS.
Unless you have no options to break into DC services and can tolerate poor ethics, absence of integrity, and occasionally hearing coworkers demeaned or getting into shouting matches, I would strongly suggest you employ elsewhere.
Personally, respect towards my basic human dignity is a MINIMUM, and this company fell far short of that.
