Sounds good in theory, redblack but:
1) "Distributing the 'burden' of employee benefits equitably" is not as easy as it sounds.
People in my last office* generally had good benefits already, but many of the childless ones really didn't like it that whenever one of our coworkers decided to have a kid, she could essentially demand to go part-time, take a year off, or work at home. Where was the equivalent benefit for the rest of us? How could we have addressed that in a collective bargaining agreement?
2) We are living in a different economic climate now.
It's not like the old days, where both America and labor unions were in the ascendancy. Competitiveness in the marketplace is a growing factor in determining wages and benefits. Workers who are too demanding of benefits will soon find themselves out of a job, benefits and all.
(Just look at what's happening to Boeing!)
You're lucky that you work in a relatively protected area, redblack. And I'm lucky that I had some money saved up . . . before I got the ax.
In this sense, however, I'm afraid we're both in the minority.
*My last 9-5 job (WA State DOH) was not in a male-dominated business. Three levels of management directly above me were occupied by women (all the way up to the Governor.)
