Pros
Fellow lab staff are incredible, some of the best people I have met in my life. Some higher paying companies see Core Lab training as a positive.
Cons
Unprofessional management behaviour. If someone takes a grievance to local management they will cover it up and label them a trouble maker. Fluids manager will regularly go into huffs and shut his office/blank staff in corridors. Mix of terrible supervisors and great supervisors. The good ones actively encourage younger staff to "get off the sinking ship", the bad ones will try to use their staff as scapegoats for their own mistakes and have been spoken to by HR for frequent workplace bullying. Low pay for lab positions, even skilled and hard-working staff will be passed up for promotion in favour of management favourites. Bare minimum holiday entitlement and no flexibility in hours even during oil downturn. Expected to do supervisors job when he has no clue what he's doing. Much of my 5 years spent there was training new staff due to experienced staff leaving when refused reasonable pay rises.
