I used to pay one week Christmas, one week Easter and the remainder in August - be be honest it didn't really work out a lot different to equal payments over the year. I'm a firm believer that my staff are fully grown adults that should be in charge of their own finances, and it wasn't up to me to arrange their pay to suit their DD/SO's for Sky payments etc!
HOWEVER covid cracked me - when we closed down march 20 I made a plan so they all got paid (no furlough available for us). I've stuck with it now as it actually makes my life easier. They get the full workings out for the year on a sheet which they sign (my job this week), this includes the deductions rate if they are off, overtime obviously paid at hourly rate. I do allow time off for holidays- so if they have already booked I can factor this in if they want.
