I get so sick of working for this company. After 2 years being with them I have nothing to show for it. I have gotten no promotions and only 1 raise. And after coming back from maternity leave, they tried to cut my hours until i transferred to a different location to get all my hours back. I work 6 days a week and rarely call off. I do manager duties when i shouldn't even be doing them. All I have asked for was 1 damn weekend off and i can't even have that.
