I worked for Hirease for several years. Was a great company before it was sold to Accurate Backgrounds. I can't really comment on working for Accurate because I did not work for them too long after they took over.
Cons
From what I hear from my former co-workers, AB started to lay many of the employees off and close the NC office, but then decided to leave that office open.
Under prior owners, the company was amazing. Like Google meets background screening. Great environment to work. Good pay, good hours, solid benefits.
Cons
Problems at the top! New owners Accurate Background ruined the company, laid off over half the workers, closed the location and then halted the closure after more lay-offs, started hiring new workers at lower rates, etc. Without the prior owners, cronyism and favoritism took over from existing Hirease management and it was downhill from there. Started going to temps, part-timers, and mediocre pay.
