My boss does not like any form of dissent in the workplace to an extreme degree. This has led to my work environment being very oppressive and recently my boss has used the tactic of getting people alone and telling them off for being negative at work or whispering in corners. Is this overstepping the line and if so, what are my rights as a worker? Can I challenge them about what whispering they are talking about? Can I walk away and say it's not a work issue? Can i say their behaviour is completely unreasonable and call in the union? This is actually oine of many issues in my workplace but we don't have a union rep atm. All i want is a harmonious workplace where im left to get on with my job. Any advice would be really appreciated. TIA.
