NOV is a company who in 2016 allowed their unethical managers in Cedar Park, TX, to fire the entire site in Stafford, TX – both engineering and manufacturing, a total of about 30 people – and transfer those jobs to Cedar Park in order to keep their own employment secure in those rough times. This cunning plan backfired, however, as the manager who got appointed expressly to do the firing, Mike "The Trout Man of Dell," got himself fired in August 2016 for failing the pee-pee test. Also fired six months after was then-manager of DDS, Dave "Winnie the Pooh," who hired Mike, who fired the Stafford crew.
Additionally, as same location in Stafford, TX, NOV kept an engineering manager, Raj "The Stafford Maniac," who would harass and bully their own employees. The bullying and harassment went on with impunity for years. The HR would not do anything with the guy despite the fact that several employees complained about the abuse to the HR. The guys was demoted eventually, however, and quit his job.
Always keep in mind when dealing with NOV. you are dealing with an extremely unethical company.
