Highly unlikely. Any BA with a sense of decency would almost never NOT sign off on it. It wouldn't be a disagreement with a personal attorney's assessment but the company's offer.
Not every local provides free legal assistance. My local provides more bennies than probably any other in the SE US but we probably couldn't provide open-ended no-cost legal council; we provide an extended consultation with one of the best workman's comp attorneys in the state at no cost to members. ADA accommodations and comp cases are exhaustive and expensive.
That being said, its potentially altering a permanent (single) FT job via accommodations and/or assignments (FT driver being reassigned to being a hub clerk for example) and the union needs to be involved.
Interesting. Hopefully I would never need an accommodation. However in the event I or anyone else did, it
sounds like we will need to consult an attorney, my local union or BA, and the company.
Thank you for the info Piedmont!
