Rumors that are likely to come true:
Back end/receiving clerk deleted
3rd party flatbed
Kitchen cabinet specialist deleted
Reorganizing of management (Fewer ASMs, different departments covered).
PSE deleted (Many stores have already deleted this position and make high volume stores cover)
The big one: Multi-department specialists. Apparently has been tested and may go into effect soon so as to improve coverage in less desirable departments and cut back on number of specialists. Might benefit the specialists who stay as they can sell anything and make SpH easier (albeit, threshold will be lifted higher) for bonus.
Less likely to happen:
Deletion of cashiers. It has been tossed around that self checkout will replace cashiers, but this is highly unlikely as many customers hate the self checkout machines due to the time it takes to scan through everything. It's also problematic for customers who buy large items (Wood,Drywall, appliances) as they can technically use the self checkout but as a giant hassle.
There may be others but those are the current ones being tossed around
