What masking actually is — and what it costs

Masking is the sustained, often unconscious work autistic people do to hide autistic traits in non-autistic settings. The research is unambiguous: sustained masking is linked to burnout, depression, anxiety, and a weaker sense of belonging at work.

Masking (sometimes called camouflaging or compensation) refers to the strategies autistic people use to appear less autistic in non-autistic contexts. Suppressing stims. Mimicking neurotypical body language. Rehearsing small talk. Forcing eye contact. Holding back on a special interest. Performing facial expressions that match what the room expects. The research literature most often cites Hull et al. as the foundational study; the CAT-Q questionnaire that came out of that work has been validated across many populations.

Masking is not vanity. It is survival. Autistic people mask because the cost of not masking (being labeled rude, weird, cold, difficult, unprofessional) is real and concrete in most workplaces. It is the reason for a thousand decisions: take this job, leave this job, stay in this meeting, speak up here, stay home today.

The bill comes due downstream. Raymaker et al. (2020) coined the clinical-quality framing of autistic burnout through a participatory study with autistic adults: 'pervasive, long-term (typically 3+ months) exhaustion, loss of function, and reduced tolerance to stimulus'. Zhuang et al. (2023) showed masking is strongly associated with workplace psychosocial harm. Diemer (2025) showed the cost is heaviest, on average, in autistic women and AFAB adults; who were typically diagnosed later and asked to mask harder for longer.

Two things follow from this for managers:

• The cost of masking is paid by the people doing it, and the org collects the result. Lower retention, lower discretionary effort, higher sick days. You are not 'being nice' when you reduce mask demand. You are running better operations.
• You will rarely see the masking happen. The point of masking is to be invisible. Your team's most heavily masking employees may be the ones you describe as 'great with people' — because the performance is excellent. Believe what your autistic colleagues tell you about how tired they are.

This module's stance is that you do not coach the masker. You change the conditions that make masking necessary.
