    Empresa em ascensão! Mas sem um plano de carreira para os funcionários.

    Analista de Atendimento

    São Paulo, SP


    Prós: Não existe vestimento padrão. Pode trabalhar com a roupa que quiser. Tem sala de descanso, café da manhã segunda, bolo e cerveja de sexta. A empresa esta crescendo a cada dia mais e é muito legal fazer parte disso. Possui um ambiente descontraído.

    Contras: A empresa não tem plano de carreira, os processos seletivos não são transparentes, tem muitos chefes. As pessoas entram ganhando um salário x, são promovidas de função, mas não recebem aumento nenhuma, nem perspectiva e nem mudam de cargo, alegando ser uma chance de desenvolvimento. Extremamente desmotivador.

    Conselhos para presidência: Ter um plano de carreira! Possuir níveis dentro das áreas. Atualmente, em algumas áreas da empresa, 90% do funcionários, tem o mesmo cargo, recebem o mesmo salário e fazem atividades totalmente diferentes, tanto em relação a responsabilidade, quanto a quantidade. Totalmente desmotivador e foge dos valores da empresa

    Recomenda a empresa: Não
