I work a part-time job (weekends only) in a takeaway for some extra cash (and free food).
I have had years of experience (on and off) within this business and they asked me to come back. Upon arrival, I was told that they'd increase my pay but this was only discussed verbally. At the end of my first shift back I received my old pay which I am not happy working for.
This is in the UK (not sure about other places) meaning that verbal contracts are just as legally binding as written ones.
I mentioned it to the employer and she simply denied ever mentioning that.
In a company in which people don't use emails, How do I get written proof (for future reference obviously this one is beyond saving as she can keep denying)?
