Toilets in the workplace

A theoretical workplace somewhere in NSW:
A staff of say 25 men and 1 female;
The workplace is being redeveloped and demountable buildings are put in place including staff toilets;
The staff toilet is a block that contains 5 "stalls" where the partitions start about 30cm above the floor and are about 170cm high;
The female staff member is told - "That's it, you can have exclusive use of the end stall if you really want to."
This would by all standards be considered totally unacceptable.

A real workplace somewhere in NSW:
A staff of 25 females and 1 male - the roles are reversed but everything else remains the same;
It is considered acceptable for the male to have to put up with these conditions.
(And the females drop toilet paper on the floor - they should never complain about a seat being left up, not that that has ever happened.)

Why different standards for female and male staff?

Just another example of the reverse discrimination that occurs and no one, including the union, want to know about it.
