SNAFU.
Sitaution normal for many 135 departments.
I worked for a 135 operation that hired a furloughed 121 pilot. She came aboard with a lot of preconceived notions, and expectations. One weekend, she was on call for the weekend. No flying, but she was notified that if a flight came up, she would be first out.
The following Monday, she went straight to the FAA and complained that she had no rest and had been on duty for 48 straight hours. She was completely out of line, but felt that it would be okay to pull a stunt like that. She got scheduled for straight nights after that.
Considering that she hardly ever flew, and had only to take a flight if one came up once in a blue moon, she had it good from the get-go. Her lack of understanding and impetuousness burned it for everyone.
Without commenting on the righteousness of her actions, let me say that the industry has fallen into a mould, and it is hardened by economics and to some degree, "tradition." Some things just "are." I am all for seeking improvement, but by the same token, there are ways to accomplish this, and ways not to do so. This particular young lady executed a massive faux paux. She should have gone to her supervisor and failing that gone up the chain within the company before doing something so drastic as going to the FAA.
I should note that the company didn't hold her efforts at change against her, only the way she went about it.
As far as 5 days a week, don't complain. Many 135 personnel are 24/7/365, period. The way it's shown on paper may be different, but thems the realities. Maxed out duty times are the norm. I've worked for many operators who had no sick time allowed, and I have been told outright, "our pilots are not allowed to get sick." I flew for one operator who allowed no time off for the first year (some flexibility for time off without pay). Nothing at all unusual, albeit unpleasant and sometimes unpallatable.
Very often I've seen regular 14 hour duty days. I've worked assignments that required 14 hours of HARD labor on the airplane when not flying, and right back at it after 10 hours rest, not to mention a number of other unpaid duties as part of the job. In salaried positions, it can be taken to the extreme. Again par for the course.
Ask virtually any inspector, and you'll get the same response; if it's unacceptable, quit. I disagree very strongly with this statement and attitude, but it's standard, and very, very common. As a function of economics, however, you're in the losing seat. The company calls the shots, and while unionization is certainly always feasible if you want it badly enough, chances are very good that it's just not worth it.
