Hello lovely mumsnetters/my own personal employment advisors 
I work 3 days a week (just changed hours when i came back from maternity leave at the start or september)
I work monday wednesday friday as thats what i was offered because it covers everyone elses days off.
My boss said he used to gov website and my holiday entitlement is 16.8 days (he is right) he then said i have to take the bank holidays out of that and save 3 days for christmas.
That leave 5.8 days holiday for a whole year, not even two weeks.
Is this right? It seems really unfair the lady i work with also only does 3 days but a monday isnt one of them and she gets all hers (except christmas so 13.8 days) to play with.
I feel like im being punished for working a monday
