I have a casual job in one place where my line manager submits timesheets on my behalf. It's my first month, i thought there would be some sort of communication to confirm my hours but the timesheets were just submitted.
He forgot to add in one of my shifts so as a result I've been underpaid £70 this month. It might not be a lot to some but it is for me.
I've emailed payroll and the answer is that I'll now receive the £70 next month.
This happened in a previous job where I was £200 underpaid and told, "You'll get it next month". I ask myself if they'd wait a full month for £200 and the answer is probably not.
They could literally do a BACS payment but it's too much hassle.
