Season 2 Edit
Josh Porter works as the regional manager of the Stamford Branch. Michael meets him at the meeting with the new CFO on Valentine's Day and he appears to be the most competent of the Regional Managers that report to Jan.
Michael seems threatened by Josh, since he is clearly his closest rival in the company and usually appears more capable and composed than Michael when dealing with corporate.
Season 3 Edit
After transferring to the Stamford branch, Jim Halpert's new boss is Josh. He served in the US Coast Guard and worked on a kibbutz in Israel. He bicycles to get to and from the office every day, in spandex cycling gear. He also plays the computer game Call of Duty with his staff, and is frustrated at Jim's lack of skill at the game.
Jan Levinson later announces plans for the closure of the the Scranton branch and consolidation into Dunder Mifflin Northeast with Josh as manager with Jim as his number two. Josh appears visibly uncomfortable while discussing this with Jan, as well as dodging Jim's questions about any of the Scranton staff being transferred to Stamford. His reasons for this soon become apparent when he admits to Jan that he just accepted a management position at Staples, having levereged his promotion into a job offer. Jan is appalled at this, and Jim clearly disapproves as well, admitting in a Talking head "say what you will about Michael Scott, but he would never do that."
Josh's departure leads to the closure of Stamford instead, with Jim and several of the Stamford employees being transferred to Scranton. Josh is last seen saying goodbye to Andy Bernard.
