Markets clear. What you get isn't what's justified or fair, but what somebody else would have been willing to offer. The guys signing your paychecks probably know better than you what the competitive market price for your labor is (because it's part of their job, and they talk to a lot more people about it). There's a good chance that having you full-time, loyal, readily available, and ramped up is worth more to them than what they'd save by only hiring you in times of need, especially if they have to convince conservative customers that long projects will remain predictable and under control. They might think only having you part-time is a bad deal, if it adds risk for them. Work is a big part of your life, and you should leave if you think you've found or created a more rewarding job. But don't leave just because you don't think you deserve what you're paid. By that standard they probably aren't any more deserving of that money.
