Change of type is significant to warrant a major project management requirement, change management, training needs analyses and large scale investment.
As seen in U.K. and NL SAR projects you cannot rely on extant crew used to doing everything a certain way a) making the grade or b) willingly adapting to new ways hence it is a method for TUPE not to be applied. If it’s within the scope for the new operator to flag as a way to avoid significant cost then so be it. That’s business. I’m sure if they are also changing a base then nobody has a leg to stand on.
We have seen, heard and read about culture and attitudes at length and no doubt if BRS are employing a manager who previously was in Ireland and found issues himself then that will play a part.
Given what has been written here regarding past experiences, the infamous events March 2017 and legacy from that including IRCG and DFT fallout then it is impossible to believe only 1 or 2 are of such an attitude etc.
Maybe @crab could elaborate on his friend’s experiences.
