My natural sympathies are with Brandy, but realities of jobs changing does come into play and what I think the 'featherbedding' argument really comes down to is that there was greed on both sides, and also distrust. Going back into the early days of railroads, the people running them refused to implement safety features like air brakes and the knuckle coupler, arguing they were too expensive, it took 20 years to get both implemented, by federal law (and low and behold, what did management find out? That by using those two tools, they could make a lot more money, beancounters were just as stupid back then as today). When diesels and other innovations made required labor needed to run a train less, instead of working with the unions to come up with a plan to re-align conditions, and through attrition and/or buyouts bring labor down to sufficient levels, often unilaterally said "see ya"....and the unions, rather than negotiating, got their backs up and demanded what they had, and no one won.
A lot of the times, rules don't change with the times, both NJ Transit and LIRR workers were operating under long haul rail rules for a long time (last time I checked, was still true in the late 80's), where what is today a routine commuter run by the 19th century rules they were using were considered long haul. A friend of mine in grad school worked for MTA as an engineer, and he said the shops had rules like that, like 'fixed rate' rules for doing something, where if the worker finished the job early, they weren't supposed to work on anything else until that time was done (so if rebuilding a traction motor according to the book was supposed to take 15 hours, and he finished in 10, those other 5 hours he would be idled)..the argument was that that time represented how long it should take and discouraged cutting corners, but what my friend said the reality was that those rules were based on the equipment and tools of a hundred years ago..but no one had the will to try and negotiate these things (this was C 20 years ago, I don't know if those rules have been changed). There is a lot of blame to go around, but as Brandy points out, when you start talking about human beings like they are a brake pad or a horse destined for the glue factory, it doesn't exactly lead to good will......
