DS had a casual job for a few days over the Summer. He provided info about his hours to a manager each day but was supposed in fact to complete a timesheet as well. HR then wrote to him saying that if he didn't get it in within a couple of days, £100.00 would be deducted from his pay. (He won't in fact be earning very much more than that.)
However, the timesheet itself says that if it's not submitted on time, payroll will simply run the following month.
As HR sent the email to someone else in error (who realized that it was for DS and eventually forwarded it to him), there was a delay of a couple of days.
I except that DS may not be paid for another month but could HR, notwithstanding its mistake in sending the email elsewhere initially, really take £100.00 off when there's nothing on any paperwork (timesheet/contract/anywhere) to indicate that this is their practice?
