I work graveyard and feel so unappreciated on a regular basis. There are only 2 of us that work in my department on graveyard and 6 others that work the 1st and 2nd shift and we on graveyard are always left out of anything that is done for the employees. Its the little things that really make me feel unappreciated. I do not expect a pat on the back for doing my job, its my job, but when 1st and 2nd shift get food brought in, you would think they would leave us a scrap or two. This I feel like is just disrespectful, just because we are not here during the day when the supervisors are does not mean we should not be included somehow. This has been going on for a long time I am just finally over it all and ready to look for a different company that will acknowledge my existence. And this open door policy, don't even think you can have a feeling or opinion because you are not allowed to get emotional about anything, you will get in trouble or made to feel like your just did or said the worse thing ever. I'm just fed up at this point. I would not recommend anyone to work for this company ever.
