The problem with abolishing DST is you have to decide if you want to have year-round summer time or year-round winter time. Many people say they want year-round summer time, but the last time the US attempted it, support for it plummeted after just one winter on summer time and DST was restored. (FWIW, scientists are almost universally in agreement that year-round winter time is the best compromise, but it's by far the least popular option.)
I'm proponent of year round winter time. And allowing changing of schedules when possible. If people want to work earlier let them or have them negotiate for that. On most areas I don't see reason why it could not be done.
