> If the (overwhelming?) majority of staff in the company are
you could replace the end of that sentence, with any number of other options:
If the (overwhelming?) majority of staff in the company are [race]
If the (overwhelming?) majority of staff in the company are [gender]
If the (overwhelming?) majority of staff in the company are [age]
If the (overwhelming?) majority of staff in the company are [non-disabled]
Its only a source of friction, if the majority makes it one. And just like the other options, it could be seen as a form of discrimination. Someone can work four days, and still be a valuable member of the team, maybe even more than "five day" workers.
