Is my work schedule hard to fill?

Anonymous
I have no confidence and always think I will get fired. People have told me its very hard to replace someone who works my hours. Do you think this is true?

Tuesday to Thursday 430 to 12am

Saturday 6pm to 6 am

Sunday 6 pm to 7 am.

I also fill in when there is sick/vacation days taken. Of course I make mistakes but I'm a team player and I always help out when I can. I'm nice to the customers and work as hard as I can. I am always proactive in correcting my mistakes
