Work flex time?

Most people buy fluff and an inflated life style
with over time pay, so, it is reasonable to suggest alternatives
that might benefit society as a whole by making some changes in time and a half for over 40 hours per week.
I suggest flex time which would allow some employees to start
work when they arrived and leave at any logical stopping place in
the task in progress. Some would work very irregular schedules of
there own choice and would be paid for the actual minutes they
worked. 5% or 10% premium pay would be offered for hours when
less than the optimum number of workers had their nose to the
grindstones. Perhaps a 10% premium would be offered when the
supervisor needed specific persons at specific times. Time and a
half would be given only for effort well beyond the call of duty.
If someone wanted more money they could work 300 hours per month
at regular pay, unless they were so incompetent that the
supervisor asked them to work less hours. Persons who chose to
average 100 hours per month typically would not be bothered by
management, as that allows more people to have jobs. The employer
would have be allowed to discriminate as some job descriptions
require punctuality, but most don't. Please suggest how this
could work to nearly everyone's benefit, spread out the rush hour
etc. With the right details, it could mean a small pay raise for more than half of the employees. It could be done as pilot programs by having employers submit their plan for permission to wave certain wage and hour rules. It woulds be very helpful for working single mothers who could change their working hours to fit the needs of their children without bothering their supervisor. It might even teach some management skills as co-workers explained how your last work schedule change impacted their tasks. Neil
