I recently came into a Supervisory position and beat out a woman 5 years my senior. Tensions between her and I are a little tense. I feel she is a time thief. Taking late breaks , and generally lazy at her job. I have gone to the boss on more than one occasion about the break issue as have 3 other co workers. Nothing is done. Except the boss pitts the Lazy girl against her co workers by saying so and so said this about your breaks. So then the Lazy girl does not speak to the person who complained. Not only that she is completely miserable everyday like she has permanent PMS which is beside the point. Why would the boss not speak to her and say Policy is..... instead of so and so said this about you. I am deep into being ostracized at work now, because I am trying to change procedure. Nobody seems to like change. I've made my bed.. I guess I have to lie in it as well. good luck.
