Access to Work is rarely fit for purpose, although your mileage may vary. The length of time it takes to get some support is achingly slow, and often relies on the NHS saying that their own products are terrible, which is hard.
Anyway, the good news is that I have had some successes recently with assessing patients privately, making recommendations for audiological interventions and the employers implementing them.
I am deeply aware that private support is not accessible to everyone, and that it should not be that way. But sometimes the solutions are cheap, simple and easily implementable. Please consider asking your audiologist for help if you are struggling to do your job due to hearing impairment or tinnitus
