Suggestions for a flexible workplace which can cater to more types of people in the workplace. 

Be able to listen and avoid assumptions. 

Don't make assumptions — ask a person's individual preferences, needs, and goals.

Avoid jumping to conclusions. 

Be kind, be patient.

Use a clear communication style:

Avoid sarcasm, euphemisms, and implied messages.

Provide concise verbal and written instructions for tasks, and break tasks down into small steps.
Inform people about workplace/social etiquette, and don't assume someone is deliberately breaking the rules or being rude.

Try to give advance notice if plans are changing, and provide a reason for the change.

Offer small adjustments to an employee's workspace to accommodate any sensory needs, such as

Sound sensitivity: Offer a quiet break space, communicate expected loud noises (like fire drills), offer noise-cancelling headphones.

Tactile: Allow modifications to the usual work uniform.

Movements: Allow the use of fidget toys, allow extra movement breaks, offer flexible seating.

Avoid hiring deliberate jerks and fire those who decide to deliberately be a persistent jerk.
