I can help you with that GA Driver.
The previous owners decided to sell the business. So to make the books look more attractive they cut back on spending wherever possible. Bristow has bought the business and soon realised they paid too much. Since then Bristow hasn’t got the cheque book out for many things and have managed to alienate the part of the upper management, including multiple HOTCs. As far as T&Cs, pilots are still on the EBA that expired (in 2008?) I believe.
The backbone of the company are the staff who go above and beyond to keep the place running. They see little to no $$ for these efforts other than knowing that if they keep the aircraft flying they’ll still have a job tomorrow.
