The WWE is helping Ultimate Warrior's wife cope with her husband's sudden death ... flying two senior WWE officials to Arizona to stand by and help her.

We're told the WWE sent the employees almost immediately after Warrior died ... their main task is helping his wife Dana handle little things -- grocery shopping, letting other family members know what's going on -- so she can focus on being with their daughters.

It's sounds bizarre ... top officials leaving their jobs to handle mundane chores, but that's how important Warrior was to the WWE.

As we previously reported, Warrior died outside an Arizona hotel Tuesday ... after suffering what officials called a "catastrophic medical event."
