“Home, home on the *****”

They should be getting 50p extra as of April 1st 2018 if that is when the wage increase took place. Also, I believe that the pension contributions have gone up by 1% as well.

I would probably have a look on the ACAS webstie/call them for further guidance, because I suspect that it is not something that can be resolved simply by going into your boss' office and asking.

Also, there will be unions which you can join. Quick google search reveals one called USDAW which may be a good option to join for future issues (they probably won't be interested in this issue if you were to join now).

You cannot be discriminated against based on whether or not you are part of a trade union.

In real terms, though, we are talking roughly £15-£20 after tax/pension is taken off for a 40 hour worker here. That certainly adds up on a grand scale, and the company will be saving a fair chunk by doing it. Though to be fair if they have 1,000 people and deprive each of them of £20 then it is only really £20,000 and that's probably peanuts compared to their revenue from sales so I don't immediately see their motivation because the risk v reward is skewed. Are you sure that they don't make a manual adjustment in the wages at some point?

Depends how much you want to fight for £15-£20 as well really... And how much it may jeopordise your ability to pick up £1000+ a month in the months to come (ie stay in the job)
