Recently the Communications Workers of America - the union that represents T-Mobile employees - contested a T-Mobile Employee Handbook clause on maintaining a positive work environment. The clause reads as follows: “[e]mployees are expected to maintain a positive work environment by communicating in a manner that is conducive to effective working relationships with internal and external customers, clients, co-workers, and management.” Their reasoning was that - if employees are discontent - they need to be able to freely air that displeasure. The US National Labor Relations Board agreed with them, ruling in favor of the union. “It’s official: employers can’t force you to be happy. Hallelujah,” cried the Guardian.
