Flexible hours, choose your schedule, good autonomy
Pros
I am part-time with W2. I get to choose my own schedule and hours - the company has consistently been good at filling my schedule when I want more and I can decline more when I feel full. I see students at a virtual school 1:1 using Zoom. The company has self-scheduling capabilities (where parents select an available time) which helps scheduling at the beginning of the school year. My manager is a good person, and very responsive to any needs I have in terms of process, school relationship, etc. but there is no micromanaging and I have a lot of autonomy which I enjoy. My manager is not an SLP, but if I need SLP related advice there is a chat "community" amongst all the SLPs that work for the same school and also for the company. I get a 401K match and PTO/CTO.
Cons
As is I think pretty typical for tele-therapists, I have to provide my own equipment (computer, monitor, internet, etc) and my own materials (I pay subscriptions to a few teletherapy game sites), and pay for my own PD. Pay is ok, not fabulous, and increases have only been about the same as inflation. The company does provide access to standardized assessments but there is a limited set available (GFTA, CELF, CELF Meta, PPVT/ EVT).
