Perhaps you don't notice how little the full-time people are trying :) It's not hard to try harder than them.
BTW now I'm curious. It sounds to me like you're talking about very different contracting that I am? I have never seen a larger company allow contractors to skip the agile ceremonies. They're always treated exactly as an employee in this regard - they're basically "temporary" augmentation of the staff, because company is not able to hire enough permanent people. (BTW this "permanent" state usually extends into years of staying at that company). Is this the kind of contracting you do, or do you do something else?
Contracting is completely different, you generally define a set project to complete, do it, and get out.
In the UK there's something valled IR35 which means that in order for you to be considered an independent entity for tax purposes you should have full control over working hours, practices, etc.
Of course, it's all paperwork that can be bullshitted, but it's had at least some effect in my experience.
GP is describing people contracted to deliver a product/service.
Do you have the money to pay a locksmith a competitive rate? Same.
Btw. Your contract will be as you make it and as your customer sign it. Thats it. Theres no point in labelling contract is this or that. Its unique per situation.
