Union membership has been declining for decades. They’re not as effective when they don’t have the numbers to back it up.

Working on the 4 day workweek in the US at the moment. Progress takes time, it's impossible until it is done.

If I had to guess I'd say UAW will get destroyed here and the end result will be more mexican factories but we will see. Seems extremely unlikely that they get the 4 day work week either way.

That's just doing 5 days of work in 4 days..

Why are you working 5 days if productivity can either be maintained or take an acceptable reduction to go to 4 days? People work to live, not live to work.

What Unions are working on this and what progress has been made?
