We are fighting for basic rights, like the right to work in a safe environment, yet SB has still refused to come to the bargaining table and negotiate in good faith,” they said.On the other hand, Starbucks said that Workers United isn't as dedicated to the negotiations as they are to rallies and the bus tour, with a representative for the chain quoting:"Even though we have attempted to schedule bargaining for hundreds of stores, Workers United has only met Starbucks at the table to progress negotiations for 11 stores. Partners voted for bargaining not buses. Perhaps that's why partners at a dozen stores across the U.S. have already filed petitions to decertify Workers United as their bargaining representative."A quick look at the Starbucks controversyFor the last few months, a scuffle has been brewing between Starbucks and the SBWorkers United, which has accused the chain of several unfair labor practices, including - worker intimidation, unfair wages, union busting, banning pride month decorations, and much more.While the chain has denied most of the allegations, as per The Globe and Mail, the company is facing at least 570 charges of union busting attempts along with unfair labor practices. Even the National Labor Relations Board (NLRB) has sued the chain for terminating over 33 pro-union Seattle employees unlawfully. The NLRB has also indicated that the chain may be guilty of at least 200 labor law violations.The NLRB sued Starbucks for terminating over 33 pro-union employees and violating labor laws (Image via Johnfscott / Getty Images)The situation seems to have caused Starbucks' reputation as a progressive employer to take a serious hit.
