Does TTD stay at the same rate with a new job?

[Vivian]

Washington state injury here.

I was injured in 2003 and received TTD for a while based on my pay at the time of injury.

I returned to work at a new job with higher pay. Recently I was put on TTD so that I could receive and recover from carpay tunnel surgery.

Should my TTD be at the rate from my old job or would it be based on my current income?

BTW this was all one claim not seperate claims.

Thank you
