Our office has been without phones for a day now - no incoming nor outgoing calls possible on the landlines. Watch how everyone (substitute this for boss people) panic. Here they are with their laptops, blackberries, mobiles and yet they act as if their right arm has been cut off. Several of them sat for ages ringing their contacts on their mobiles telling them that their mobile was the only way to contact them - so anyone else trying to get through, couldn't. Quite amusing really, for a Friday
I think it is because what is always there is suddenly not and in their mind, they are missing out.
I on the other hand have enjoyed a quiet(ish) day because of this.
