It can be squared.
Its based on proportionate adaptation on the right to change not the righ to change beside somebody else.
But looking at it from both all sides from the top down.
Provision
Population
Individual
The individual gets fair access to the same level as any member of the appropiate population.
Take a wheelchair user (PC Disability ( D)) in employment in an old building
You are not expected to replace all the stairways and doorways in a building with lifts and proper clearance openings.
You can be expected to have a ground floor office that is accesssable and a toilet that a wheelchair user can access
The exception would be where the cost to adapt would cause harm to or actual business failure.
Similar a Muslim (PC Relegion (R))who wishes to pray the provision of a space and allowing time is proportionate once it can fit around the role.
The NHS has failed to grid the PC and create a rule where they clash.
So the whole employee population would split down into very small sub-groups using the 9 PC into Are these PC and Are / Not these PC.
They went GI Only and ran the proportionate test
Policy should be based on looking for all the outcomes possible before they happen.
Eg
Why CR:
CR are health and safety issue its infection control for staff leaving the work area and allows replacement of damaged protective gear after a work place accident.
[The policy should have all the legislation that is relevent to each decision. As the law will stop the "decision tree Yes" to a No because its unlawful.]
So building regs and H&S laws quoted.
Outcome: Fife need CR
How many CR
We look at our sub-groups and decide what provision is needed
PC : Sex (S)
Law says SSS
The doctor male need to use a CR is provided for.
Every other employee is provided for to per the law.
Fife must provide 2 CR per the SSS law and PC S has only 2 class
Outcome 2 SSS are provided
PC: S and D
Here the SSS law still applies and proportionate adaptation
There is a need to make the space user friendly or provide a dedicated space
So quoting SSS lad and building regs for space and fitout and etc..
Outcome 2 SSS are provided both with access or 1 individual unit is provded with access
PC: S and R
Here the SSS law still applies
Plus some faiths do not allow nonSSS CR so no clash.
So SSS law and how free expression is allowed/restricted eg there should be no symbols and guidance on matters of faith eg no abortion posters or bible quotes.
PCs: S and GR
He or any other male can not be in the female single sex CR as the SSS law says no.
So hospital need to decide if they provide a 3rd space. That is a right to a not-male CR
(What happened in the US was a school decided the girls had no right to contol who had visual access to their bodies if they changed on the school premises. And the school district were going to payout 3m ish to the boy who wanted access)
PCs: S and GR and D
So what happens in the third space if and someone has a disability
PCs: R and GI
Here non-SSS can be a supression under R so they need to provide for both parties
And each of the PC gets mixed and matched before the policy comes into being so case-by-case is never needed due to the pre-anticipation and resolution.
The law at the moment stops males. And i cant see the ET ruling otherwise
