Should America transition to a four-day workweek?

Pay needs to be increased if this happens as people budget for working 5 days and the school system will have to be looked at as students need 5 days in school

Yes but it should be up to the company to determine the suitability of the 4 day working week to their business requirements

Yes, but within reason regarding the sectors/type of work. For some it is just not viable, and therefore unfair on the employee to earn the same amount in a 5 day week, as someone working a 4 day week. But is also unfair on the 4 day worker to have reduced pay if completing the same amount of work as they would in a 5 day week. Also unfair on the employer to have to pay overtime for the person working a 5 day week, when this is typical for the type of work/business.
Needs to be carefully discussed and implemented in a way where satisfies all involved.

Yes but not for teachers in schools to enable maximum learning for children. However, teachers should overtime should be paid for the fifth day of school for teachers.

Depends on the job. Teachers students lecturers snas etc. their job can unfortunately not be done in 4 days they need the time and contact hours with students

A three-day week would be more practical; it would free up people to deal with the many random issues that they would otherwise have to take time off work to deal with.

This would be nice but is not a pressing issue for Ireland
