I received a letter stating that 'with effect from 1st July' I would be entitled to a bonus 'which will be paid in the July payroll'. It then states 'please note that you will not be entitled to the bonus if you resign before then'. I resigned shortly after the 1st of July, but assumed that I would still get the bonus as it was 'effective from the 1st'. Just received my pay minus the bonus and they are saying I am not entitled to it. What do you think?
