Undertaker demanded every wrestler treat WWE like a sacred place — no trashing the business, no ego, no shortcuts.

If you were late to call-time, Undertaker always found out. New wrestlers who arrived late were immediately on his bad side.

Taker hated bragging. If someone acted like a star before earning it, he would publicly shut them down.

Backstage drama, relationship fights, or attitude problems were not tolerated. If you walked into the locker room, you were a professional — or you left.

Rookies were expected to shake hands with everyone, especially senior talent. Ignoring this meant you disrespected the entire locker room.

Especially during the Deadman era, Taker expected wrestlers to protect characters at all costs — even in hotel lobbies and airports.

From referees to ring crew, everyone deserved respect. If someone messed with backstage staff, Undertaker personally handled it.
