Season 9: Episode 203: The One Where Rachel Goes Back to Work
Monica helps Chandler consider what careers he's interested in. He choses advertising, and Monica arranges a meeting with a friend (Steve) in the business. Joey gets Phoebe a job doing extra work on Days Of Our Lives, but she takes her characters a little too seriously. Ross and Rachel take Emma into Ralph Lauren to meet the staff. While there, Rachel discovers that her temporary replacement (Gavin) it determined to take over her job permanently, so she returns to work immediately. He turns out to be a little nicer than expected. Chandler gets offered an unpaid internship at Steve's agency, which might mean he and Monica need to postpone having a child for a while.
