When you say "everybody has a 40 hour contract" does this mean that you are the only part-timer?
As Astichintime and Cossy say, you must get a proper written contract. One which spells out your hours and your responsibilities, it is a legal right of any employee. You also have the right to a meeting with your employer and you need to ask for clarification particularly you need to know if it is a fixed term contract or a permanent one.
Were none of these matters discussed at interview?
I am the only part-timer I suppose or think so. So seems their HR needs to study a bit a part time contract making.
I am given the task I can physically manage and is a current ongoing business need.
I am into the system and have payments, slips, holidays etc.
Just not sure what my boss plans for me and my position is. Might be just a mercy: Let's give the lady the job which she can manage and so on
