Due to go on maternity leave in a few weeks, my workplace is restructuring at the end of the year due to a loss in funding, under the new structure my job doesn't exist. A similar job has been created which I presume I will be offered but its full time and I currently work part time (3 days a week) Due to childcare there's no way I can accept a full time position. Is this valid grounds to reject the alternate job offer and claim redundancy instead? I have been with the company 2 years.
