NEW York Yankees delivered a “slap in the face to all Bostonians” on Thursday night by crossing a hotel strike picket line.

Boston hotel cleaners, cooks, bar staff and countless other employees are on strike demanding more stable hours, protection from job losses due to automation and new sexual harassment protocols.

The Yankees arrived in Boston before their play-off match against the Boston Red Sox last night but, instead of checking a list of socially responsible union hotels nearby, continued to check in to the Boston Ritz-Carlton with striking workers chanting: “Don’t check in! Check out!”
