What drew you to this job, to begin with? That's a lot of traveling to have an employer behave abrasively. I once took this course on corporate social responsibility. It involved studying ethics. The Golden Rule, happens to be a top ethical standard. As a manager, I'd personally, prefer that all of my employees were sensitive to the plight of one another. Any employee traveling two hours just to be there deserves a lot of consideration. Retail or office, the internal culture truly shouldn't be any different.
Your boss, do they realize they don't have a healthy group? Noone needs to be friends, yet, everyone needs to be professional and display respect towards one another. It trickles down to the customer and trickles up to the big bosses. I understand not everyone can be a leader, but it's not up to your coworkers to behave towards you as if they control the schedule/company.

With that performance review and your autism what's this drive to need to work? In the states, if you are disabled, you're disabled.
