Unless minimums are set by an outside force, such as the FAA, hiring minimums will always rise and fall based on supply and demand. When airlines, either major or regional, need pilots to fill their seats they will hire whatever they can get. If manpower planning or whatever they are called at your airline, tells flight operations that they need 100 more pilots then they will find 100 more pilots. No airline management is going to willingly cancel flights because they cannot find quality pilots, instead they lower their standards until they get what they need. This is true at all levels, major, regional, corporate, cfi, etc.
