As others have said, you're not getting a great deal from a straight money for time perspective. It sounds like you're working in a standard traditional therapy practice setting where you schedule patients for an hour *45-53 min," get nothing if they no show, and if I'm reading this correctly you're doing two part time practices across a 5 day work week? On another note it appears you aren't salaried
Consider what's more important to you time or money?
Do you want consistent pay and benefits or do you want more freedom and flexibility with your time and how you spend it?
I learned, perhaps the reality check hard way, that salaried work, especially in more traditional therapeutic one hour of therapy per patient often comes with burnout heavy productivity requirements and conditions. With little control over no shows, reschedules, etc. Sure you might get PTO, health insurance, and some other benefits but at what cost? You're often made to work 5 days a week 8+ hrs a day leaving little time for a side practice or side work should you want it with work/life balance. I know quite a few psychologists more than happy to make their $70-95k a year salaried 35+ billable hour a week required group practice jobs, but plenty others where it really doesn't go with their lifestyle and expectations. Neither is incorrect but one should know what they're getting into.
Figured out that, at least for me, W2 FFS work and some side contract work is the path for me. I'll gladly pay my own health insurance, take time when I want and how I want, and work less days per week. Freedom, flexibility, less stress about meeting some "numbers" to "earn my salary and benefits" were worth a risk of lower yearly income for me. But I also focus mainly on work based in healthcare systems and facilities with some limited group practice side work. So if a day is slow or can't work that day I can choose to "make up" the lost revenue if I want another day. I also feel better about knowing if I want to pivot, adjust ratio of time spent at one "job" over another, or even pick up some adjunct teaching or consulting I can make a change more easily. There's no 'moving up' or "career growth' in the traditional sense in many of these jobs, unless one wants to get more into the administrative non-direct work, but that's ok with me.
So another question to ask yourself is do you want to be a practitioner/provider mainly or do you see yourself "moving up" in an agency, company, etc and being a supervisor, boss, manager, or something like that?
It looks different for each person and sometimes it's trial and error finding what fits your life and expectations best. But others are right, you're not getting a great deal in your current situation and likely leaving opportunity and potentially more income on the table.
