As a disabled person, it is so nice to hear that despite the EEOC publicly available resources that say an employer can tell other employees that accommodations are due to the needs of the business or due to federal law but cannot say it's because they are disabled, you got your HR person to actually say flat out the two TMs are disabled.
Seriously, did you need to violate the privacy of those TMs? If they told you, it's one thing, but if they didn't, they clearly didn't think you had any right to be all in their business.
We exist. Accommodations keeps us paying taxes, instead of you paying our SSI/SSDI and Medicaid and your taxes getting raised because more disabled people need those things.
And while I'm not sure I said it to you specifically, I always point out the possibility of a disability and accommodation whenever someone complains of favoritism. The concept should be floating around here and also in your life. Did you really not think about how front end folks could have hidden disabilities like your proverbial cousin or best friend or family friend does? Or do the folks you work with just have to be healthy to have the job in your mind?
Are you next going to complain about bathroom duty until you get told that there are TMs that have hidden disabilities that need to stay away from E. coli?
