My new employer has agreed to pay for my fees (tuitions only) owing to the old company once I end my contract with them for a maximum amount of 10k, but it turns out I only owe 2k. However I also have 8k of maternity top up fees owing to the old company that I haven’t discussed with the new employer. Is it okay to ask to see if my new employer can cover my maternity leave top up by the remaining 8k? Or does it look bad?
It's best if you are crystal clear with your soon-to-be employer, so I suggest you do tell them about all details and things that sum up to what you owe to your current company.
Fortunately, seems that 2k + 8k = 10k so it's not like you would be asking for more than your future employer is willing to pay. However, it's best to tell them so there are no surprises.
