I get what you say.
For example, procurement. It is not really part of my job. I used to get the quotes, because it is specialist parts. Then there was someone to place the order, one to approve it and one to sort the invoicing, payments and deliveries and credits, and so on.
Now, I place the orders in the system, my manager approves it, the automated system sends the order to the supplier and pays when I receipt it.
But.... if there is any issue, it is all down to me. Contact supplier, sort invoices differences, sort credits for the invoices, cancel orders, deal with lost orders, deal with deliveries... And.... if something has not been paid and our account is blocked! All that on top of my actual work.
It does not sound like much. And it is not really, when all goes smoothly. But when there is the slight issue, it takes a good chunk of my day, while I am meant to be doing something else. And that becomes stressful at times. Particularly if our account is on stop. Because, as I am not the actual finances contact, I only find out when an order does not make it to us. That can take endless phone calls and emails. Plus delays on my actual job.
I think many roles are this way now. The accounts site person is gone. The one who used to sort orders and supplies and invoices for all on site, and deal with the finance team regarding stopped accounts and invoices. That person is gone. And their 7 hours a day are spread between all of us on site.
