I use the salary sacrifice scheme (childcare voucher scheme) to pay for part of my childcare. When I started the scheme HR sent me a letter confirming the details, which also said that any future pay rises would be calculated net of the sacrificed salary. My pay rises recently have been a cost of living percentage (rather than a fixed amount) so I'm losing out a bit. Is this normal procedure?
Obviously I'm gaining overall with the reduction in tax so I'm not going to stop using the scheme, I just feel it's a bit petty on their part.
