Immediately post the shift in the swap board. Hours are being cut so there are plenty of people that will be looking for shifts. In my store, there are a couple of team members that check the swap board before and after each of their shifts and before and after each of their breaks. They are always checking and always picking up shifts.
Be proactive by looking at the swap board to see which team members are picking up shifts and ask those team members directly if they want your shift.
Go through the posted schedule and see which team members in your area are off that day. Be proactive and ask those team members directly.
Immediately speak to your ETL, HR, or Store Director. Explain the situation and ask if they can take away your shift or know someone that would want your shift. Depending on your area and the time of your shift, they may want to save the hours rather than having someone pick up the shift.
If they won't and you can't get someone to take your shift, just call out. If you have never called out and have never been late, then one call out for legitimate reasons should not be the deciding factor for being kept or let go. If they aren't ok with you calling out, then they probably won't be ok with you calling out in the future should you need to attend a funeral.
This is a seasonal job. Sure Target pays more than many other seasonal retail jobs, but it is still a seasonal job. Target is not your life and is not the only option.
If Target doesn't want you or doesn't treat you with respect and common courtesy, take your talents to another company that will treat you with respect. I am sure there are plenty of other retail stores in the shopping center with Target or right by Target.
Also, if Target gives you a hard time about calling out, make sure you tell all your family members on New Year's Eve. Tell them to stop shopping at Target. Tell them to tell their friends and coworkers to stop shopping at Target. As a consumer, you do not have to spend your money at Target.
I have been fired and laid off from companies in the past. I have never spent a penny with those companies since they fired or laid me off. If they don't think I am good enough to work for them, then I don't think they are good enough to buy their products.
