This new working schedule will take sometime to work itself out but many compaines will be doing the same. Thus an employee will work 28 or less hours at one company and pick up additional hours at another.
Just because it is only 28 hours does not mean it won’t be a 5 day a week job. Employers want full availability. Finding 2 compatible part time jobs can be difficult especially in the service industries.
It’ll take some working out but many people work a couple of jobs now. With many companies rescheduling their workers time to max out at 28 hours/week there will opps for working two jobs. Ingenuity will show itself over time.
