Family Dollar complaint: Completely left off work schedule

I work for the store 06109 Tylertown Mississippi. I have worked There since October 2019 with no problems. I have enjoyed working for the company and tried to work in the best interest for the store and the company. This makes the second week I have been left off the work schedule with no hours or being told why. The schedule is posted week by week usually on a Thursday. I gave the the manager my work schedule from my other job for two weeks before she made out the schedule. This has not been a problem In the past. In the past if she changed my schedule I asked her to inform me so I would know…I snapshot the schedule. I am not aware of any problems with the manager, coworkers or costumers with me. New people have been hired and time given to them. I work the company’s rules unlike my other coworkers I wear my mask ,I unload trucks and I try to get to work on time .
