a search of the archives would have turned up the answer, if for no other reason than that many of the PPs on this forum, which you and I are not, are FR pilots.
While CRM is not FR's forte, see various union and employee relations issues previously, MOL has cut everything but safety, maintenance etc. FR's safety record in terms of flights/seat miles etc. is more than adequate.
Questions have been raised about FR's practices on hours, aircraft etc. but so far so good. As for FR being the largest 732 operator, this is probably since Southwest binned theirs for being below a critical mass of planes for maintenance, pilot cadre reasons (they reckon 25 is the minimum of any type they want on their books).
Look at the industry - they are matching MoLs practices. If he's wrong, so are they. Maybe so!
