The Oregon House will vote on a three-tier system for a minimum wage today, but talks behind the scenes involving Republicans and moderate Democrats could lead to a new proposal.  52nd District Representative Mark Johnson has been a part of those discussions, and says there is a lot of interest to find something that could find bipartisan support.  He said such a package would continue to allow Portland metro area to head towards a minimum wage of 15-dollars-an-hour, while the rest of the state would top out at 11 dollars.  The Hood River Republican added there could also be consideration of adding a training wage.  Johnson did say he expects the current package before the House to pass today, and it has already been approved in the Senate.  House leaders earlier this week said they wouldn’t consider changes until the current package is passed.  Senate and House Democrats have pushed for the three-tiered minimum wage jump, saying they believe a November ballot measure that would increase the wage to 15 dollars an hour across the state would pass.
