The Equality law protects people from being called a pronoun that doesn't reflect their transitioned status
This is not true, as BetsyM00 stated above.
Technically what BetsyM00 said is correct as a statement. But that law also makes it explicitly clear, including for gender reassignment, that people should not behave in the workplace in a way that is:
(i)violating B's dignity, or
(ii)creating an intimidating, hostile, degrading, humiliating or offensive environment for B.
in deciding whether conduct has the effect referred to in subsection (1)(b), each of the following must be taken into account—
(a)the perception of B;
(b)the other circumstances of the case;
(c)whether it is reasonable for the conduct to have that effect.
This is true for any of the protected characteristics. Why would you not want it applied to all? In most real life cases referring to someone as the opposite gender to which they (feel) they are presenting as would be taken to be clear harassment.
