Well, theirs doesn't: it falls outside the purview of OSHA via the loophole of not being in the US :-) In fact, the relevant UK legislation is marginally stricter, and permits up to 50 people at work for 3 unisex toilets: http://www.hse.gov.uk/contact/faqs/toilets.htm http://www.hse.gov.uk/contact/faqs/toilets.htm . That's five fewer than the US Labor Code. I did note with amusement this line in the US code: (2) Construction of toilet rooms. (i) Each water closet shall occupy a separate compartment with a door and walls or partitions between fixtures sufficiently high to assure privacy. US toilets gave me quite a culture shock: the partitions and doors are so short, high off the floor, and full of gaps that they certainly did not "assure privacy", at least not compared to what I'm used to.
