The company gives people too many chances to correct poor performance. Literally watch a person refuse todo work cause he was doing college homework instead of helping out when the network team was slammed. They tried to give them multiple chances to improve after that. Then they left when scheduled to rotate to nights.
Tier 3 offer training to anyone who asks... Most don't ask; then complain about not getting enough training.
Moral of the story is most of the 1 star reviews seen on here are people who failed to adapt to actually working after getting out of the military.
