Inappropriate action by the CM of the company: The Community Manager of the company, who is not conscious of acting under its corporate profile, issues a personal assessment of a subject about which the followers of the brand it represents are particularly sensitive.

In his comments echoed thousands of people to unleash a stream of negative opinion true to the brand. Must be made aware that workers are direct counterparts of the brand and of course, keep them happy and meet all current legislation regarding occupational health, recruitment and any other aspect of employment. They deny the facts:The company flatly refuses to admit that your company is going through a serious economic situation, a fact that is clearly more evident. Instead, opt for trying to appear normal and live apart from the comments that boil in the network.
