1. State of the WEB ‘18

2. Be excellent to each other.
Treat everyone with respect. Participate while
acknowledging that everyone deserves to be here — and
each of us has the right to enjoy our experience without fear
of harassment, discrimination, or condescension, whether
blatant or via micro-aggressions. Jokes shouldn’t demean
others. Consider what you are saying and how it would feel
if it were said to or about you.
Practice saying "Yes and" to each other.
It’s a theatre improv technique to build on each other’s
ideas. We all benefit when we create together.
Speak up if you see or hear something.
Harassment is not tolerated, and you are empowered
to politely engage when you or others are
disrespected. The person making you feel
uncomfortable may not be aware of what they are
doing, and politely bringing their behavior to their
attention is encouraged.
In case you see or hear something or feel
uncomfortable, reach out to dev-mena@google.com
