I want to return to work but cannot make full time work because of the long commute to London. However I was told by my employer that I had been accepted for a client secondment role which would enable me to work a 0.6FTE provided I cut short my maternity leave by 2months. They wanted me to start at short notice so as soon as I got an email confirming I had been selected by the client I booked childcare. The client has now changed its requirements and my employer is refusing to confirm I can still go back to work on the date planned. This leaves me with a huge childcare bill.
Does anyone have any useful advice? Could I take this to an employment tribunal or would it just be dismissed on the grounds I didn't wait for a variation to my contract prior to booking childcare? If I had waited I would have been unable to fulfil the role had it happened due to lack of available childcare.
