Can an employer do this? - Pay Related

[BrokenBananaTantrum]

My DH has been working 2 days a week at a shop for the last 4 years. He works Wednesday and Friday. Pay day is Friday, so he has always had his wages in cash on Friday at the end of the day.

His emplyer has now decided that everyone has to work a 'week in hand' so he will not be paid this Friday but the Friday after?

Can an employer start this after 4 years?

Thanks

He is working a week in hand - he gets paid after he has done the work, not before.

In terms of varying terms and conditions, it depends on his contract. Varying pay dates isn't unusual per say, but it's usually done after consultation and with notice. Under these circumstances, I'd wonder why.
