So you're saying an RPCD can be laid off and do 2 PT shifts and make less than a 22.4 because he is not a 22.4 and 22.4s can never be laid off.
First of all, for a RPCD to be laid off, you would have to have the entire bottom 25% of your center working in the building, ZERO 22.4s or TCDs driving.
After 7 days, the RPCD would get the inside full time rate. Remember they get slotted into progression.
The lowest paying top rate for inside work right now is car washer ($39.45+COLA). Top rate for a 22.4 is $34.79+COLA.
It’s possible but highly unlikely. You would have to have a topped out 22.4 (I haven’t met one yet), and a laid off RPCD that’s still in progression, both working in the building at the same time.
