A typical sick out phone call at Air Canada:
Me: "Hi, I'm sick."
Crew Sked: "Ok, what's the employee number?"
Me: "12345"
Crew Sked: "OK, hope you're feeling better soon. Give us a call when you want to book back on."
Me: "Thanks."
Of course there is the caveat that if I am sick for more than 7 days, I have to get the ok from the company doctor before booking back on. Also, we only get 90% of our pay when we are sick.
