McDonald's

Good day everyone. I'm a regular employee at mcdonalds canada at 1890 innes road. i have my benefits. i have my own family and we are renting. they always cutting my hours there. i don't know what to do anymore. they don't care. the manager who is doing the schedule told me to ask the restaurent manager regarding my hours. i told them i should have enough hours because i am regular. ive been working at mcdonalds since i came here at canada 4 years ago.i need to stay regular because i have a family, i have a rent to pay and i have benefits and i dont want to loose my benefits. they said they cut my hours because theyhave lots of new people and that is unfair to me because why keep hiring but cutting my hours?they said i can't complain because is unreasonable. if anyone can help me please. i'm 20 years old and i'm not that smart but i know what is right from wrong. please help me. the restaurant manager said she can't do anything about it. but she need to do something because it is her responsibility because i always do my job right. i am a crew trainer and ive been awarded for best employee so it means i'm doing my job right.i'm hopeless..im already looking a new job but i have to make sure first. it happen to me many times already. but they said as always i cant do anything about it because the restaurant manager cant do anything about it..please help me.someone.
