I've just started some casual work at a company that does stocktaking in shops. They pick you up in a company minibus and then go to a different shop on each shift which lasts as long as it takes to complete the job. Shifts are decided a few weeks in advance. I was due to work today. I get a text from the driver before each shift to confirm the pick up time as a heads up, although the times are already known a few weeks prior when you agree to do the shift.
So yesterday I got a text saying 'Sunday pickup at your pickup point Sunday 2.30- drivers name ' , as normal , then shortly after
'Hi, change for Sunday pickup was 2.30 now 1.30 - drivers name'
I just read it and thought OK and didn't think anything of it.
Then this morning I went downstairs left my phone in my room and didn't check it until 10. By that point I had a text from 8.30 saying
' New pickup time at 1.30 please confirm you are working today-drivers name' and then the next saying
'sorry had no reply had to replace you'
I rang the driver who said I should have responded to the 'Hi, change for Sunday pickup was 2.30 now 1.30 - drivers name' text to confirm I could still do the shift, but it didn't say please confirm and I just thought it was rhetorical factual information about the pickup time for the shift since it's already been arranged 2 weeks in advance.
AIBU to think replacing me for the shift was harsh? Obviously if it said please confirm I would have immediately responded but usually they're just heads up texts and I wrongfully didn't think they expected a reply.
