IMPACT contract with TSA is already experiencing layoffs less than 2 months after starting the contract in February 2019. My guess is they over hired staff with repetitive skill sets.
From what I’ve seen, they have given folks 1 week to either find a new job or be relocated to a different contract if a position exist that matches your skill set.
CACI took over the TSA contract by charging $194 million for three years. The former Incumbent company (GDIT) was charging close to $400 million, so my suspicions are, CACI is trying to cut cost.
