Each to their own, but for me....no.
The option of a self check out for me means I can usually beat waiting in the que. Time is money for many of us, and blocking the front end of the store with all of us waiting is not helpful, particularly on busier days.
It is not the stores just dumping staff, but wages are a huge expense, and if they choose to operate the store and not replace every lost employee, well it is their business and their right.
I can't put stock out on shelves, but I certainly can scan a few bags worth, and I do around 70 items every week, on C/O #114 at Coles.
I also get my bags packed MY way, hard and heavy on the bottom, soft and light on the top and in the order I want/need them packed.
It is a bit slower, but I am not an expert, and this is all part of my choice.
This also helps keeping item pricing down with not having extra staff on a checkout, and the expense of maintaining a full sized check out, and the extra floor space made available as self serv' check outs are smaller.
It all adds up, use it if you choose, and take advantage of the choice we have now, which was not available years ago, and does not cost us a cent extra.
Now, how about self loading/driving trolleys?
