Dharmattan Nig. Limited review: rip-off and discrimination

My friend worked for the above-named organisation and was treated in the most unethical manner.
The company is a contractor to Chevron and recently it issued letters 90% of its staff members that their employment would be subject to review every six months effectively changing their status to casual. The company has no health plan or any form of benefit for its staff.
Recently the Managing Director of the company and his wife had their US visas canceled and her currently under investigation by the US state department for money laundry. His gender discrimination is evident in his employee assemblage. Presently, he has no woman geoscientist on his team.
I will like that this company be reviewed so that the unscrupulous practices now employed by most business owners in this part of the world is checked.
