hey,
how many jobs are we talking about?

just off the top of my head, I find it hard that every job you get hired at is a toxic workplace...that is a rare set of odds. perhaps you are applying for jobs that do not suit your personality.

you know...getting treated with respect sometimes means you need to treat others with respect. that means going into the job with more then displeasure from day one. just saying greetings is not enough. if you decide you hate the workplace from day one then your attitude will shine thru. people are not stupid.
something else..i understand needing accommodations..but just how are they not meeting your needs? you said they gave you earbuds at one point.

if you present yourself as hating the place, being miserable and close to cracking from working in a hellhole...and perhaps not pulling your weight then other employees will not help you out. most times employees will at least help newbies..but if you have come off as complaining and miserable since day one, your chances of co employee support are slim. do YOU help THEM?

is this your first job? is it a corporate chain or a mom & pop shop?

how do they treat you like a servant? do they tell you to do things? perhaps since you portray yourself as so miserable and barely able to function they feel that simple directions are the only way to get their point across. putting trash in the dish bin happens at restaurants...so does dishes in trash. especially during busy periods. no one is perfect.

you won't get respect until you earn it. sorry to say it seems your attitude won't get you respect. praying that you might make a big enough error so you get fired and not have to work there just doesn't cut it. you want to be a valued employee? just thinking those thoughts won't ever get you there. hate to say it but it's a job. it pays the bills. it isn't supposed to be a fun, happy respectful place where everyone plays nicely. it's great if it works out that way, but it is supposed to be a place that sells their product successfully. period. if the staff plays nicely. bonus points. you can't MAKE anyone like you or respect you. you earn that. FROM DAY ONE.

I understand the disability thing. got one myself. it's hard to get accommodations at times. some times it's a struggle. but I am so much more them my disability. I have worked some pretty crummy places throughout my life. that said..each one taught me a lesson. you probably aren't going to make this place your career but it does pay bills, give you some $$$. so for now, while looking for another job, keep working. be the grown up.
