The company that I work for is structured a tad weird. There are only a few actual employees for the company. Everyone else (including my manager) is "hired" through a separate agency. When I was brought on board, I was given the offer from the main company. Then they referred me to sign in with the hiring agency, who processes all the payroll information.
Now they want to switch me to a different hiring agency within 90 days (the employees here are split between 3-4 different agencies) to consolidate everyone. This will be a full W2 position through this agency.
I was told they would at least match my current pay, and I still get no benefits.
My question here is: would it be inappropriate to ask for a higher pay when submitting my paperwork to this new company? Also how would I ask for a pay raise in the future?
