Get your union involved. I had this issue with someone who was trying to get their dream schedule and I had to over ride their authority. Because I couldn't do appointments nor participate in family life. If you have any schedule restrictions it will penalize you. If you're in the front end as a cashier you should be able to pick your schedule. If management picks it for you they are breaking contract rules. Other departments I'm not sure. seniority always rules over others. Get your union involved
If you either requested a day(s) off or have an unavailability on any day, then you have no case. If the other person is scheduled on the day u asked off or unavailable, you can not jump there hours for that shift. I have gone through this with one of my clerks. They were unavailable 3 days of the week which caused them to have fewer hours that someone with less seniority. They would go to management and the union but was told since they are unavailable for those shifts, they don't have a case. I had to schedule someone else to work the days they couldn't, which caused them to end-up with more hours.
Did you talk to your new front end manager or management or shop steward? I would start with the new front end manager. Writing a front end schedule is sorcery more than science. E-schedule does stupid sh* t with hours and doesn't always get seniority correct.
Make sure you know your contract well. I've had people complain but they were unavailable or requested off. SORRY, NO. I had one who wanted to roll for shifts but trying to take shifts that were outside availability. SORRY, NO. Available fewer than the minimum hours? I'm not going to schedule you period exactly like the contract dictates.
We've been through a period where hours were cut so badly it became a war of rolling hours. The schedule writer had to waste time adjust schedules to block rolling. Shifting someone 15 minutes one way or another to keep them from being rolled. Making it so if they lost a shift it would put them below minimums so someone who wanted to roll had to take their whole week but couldn't because they worked on a same day. PAINFUL. TIME WASTED.
