If the company is of the size that they require THAT much out of the CP, they usually have a receptionist answering the phone for him, there should also not be a published line to the man in charge either. Use the receptionist or the main line and have whoever answers it, be bright enough to deal with random pilots calling. Some of the larger companies (borek is one) utilize someone who is great at running block for the 'chief'. Hell you cant even walk in to the office to say hello without first passing her... so bring flowers, or chocolates or donuts.. wait.. bring all three! You can bribe the other pilots with the donuts till they agree to show you around.
If I see a "no phone calls" line for an ad at a place I wanted to work.. I'll pop by in person, the phone is even still too impersonal.
Plus I wouldnt want to work for a lot of the know-it-alls and others that may frequent this forum if they dont have the decency to talk to me in person. How am I supposed to approach the CP or OPS mgr when I'm flying the line with a real problem if I cant even approach him about some of the pertinent job specifics. communication in the work place is key.
This still does not mean I'm going to call or walk in without having first researched the company. I'll KNOW what types they fly, roughly what the pay is, what the schedule is going to be like, the type of flying and the general reputation. Its a small industry, word gets around. Dumb questions should get smart ass answers!! All the info is out there if you look for it. Dont be a lazy SOB!!!
Alright, Rant mode off.
