What a nice rant there ritakk.
But you weren't talking about people accepting additional workload.
You've added that in later on.
You were talking about not accepting dyslexia 'as an excuse' if issues arise.
Again, see the word accept and again, the whole post that you selectively quoted from and the follow up post explaining the issues.
If they'd be somewhere unlikely to appoint based on someone accurately disclosing dyslexia at the right time in the process, they're not going to he an understanding workplace.
Or to put an even more blunt spin on it, if someone lies about having dyslexia to get a job and the then a school may be less likely to accept "but I'm dyslexic" as an excuse if issues arise because the candidate chose to lie to the school.
Picture this hypothetical situation:
Candidate lies to get a job, then after getting the job downplays or lies on their new starter forms. Teacher is now in post and finds they're being picked up for literacy errors in their marking, their lesson materials are regularly full of errors and parents have started to call the HoD. Reports are due and they are also full of mistakes because the teacher hasn't had time to proof read them all. Over the course of a term or two, there are concerns building about the teacher's capability. The HoD has to have a meeting with the teacher to raise performance issues. The teacher then says "but I've got dyslexia and I don't have time to check my materials and the reports were too much for me to proof read. I really need someone else in the team to proof read my reports for me". This is the first the HoD or SLT have heard about this teacher's dyslexia.
And my post after it:
I'm not saying they shouldn't make reasonable adjustments, just that there's space in the process to declare disability that requires adjustments.
For my current job I declared mine on the new starter forms after I had a job offer, and had a discussion with occupational health before starting.
If we're thinking about professional relationships then someone choosing to tick 'no' to a disability, not give work an opportunity to put appropriate adjustments and support in place isn't going to promote positive working relationships if their actions cause lots of additional workload for colleagues, and has an impact on the quality of their teaching (which also creates additionalwork for colleagues).
The amount of additional work when there's parental concerns about a teacher can be huge, and can easily be avoided if someone mentions they need adjustments at the numerous times given instead of saying nothing until concerns about their performance are raised.
At the end of the day, there's ample opportunity for people to disclose at appropriate times in the process, honesty at appropriate times is best, and (as I said) a workplace that would be poor when disclosures are made at appropriate times is also not likely to be the sort of workplace to be accepting should performance issues arise later.
