Just after a bit of informal advice for my sister.  She recently applied to reduce her full time hours to four days part time under the Statutory procedure to begin in June.  Employer held meeting within the timeframe, agreed new working arrangement at meeting, wrote an email to that effect.  The problem is the employer has not come back with an official HR response, only just the email from the HR representative. Is this sufficent to constitute an acceptance, in the absence of any other document provisioning? The fourteen day limit for this response has now expired, and it is infact 15 days since the fourteen date timescale expired. My sister has contacted me in tears today to learn that her employer now plans to renage on that agreement, and subsequently decline her working request – yet no letter confirming this has yet been provided.   This will cause her problems since she has arranged and given notice to her nursey and may not be able to get the place back for the intended non working day.  The HR department have ignored all of her requests to be provided with this formal letter that she has sent since the fourteen day timescale expired, and all she had to go on is the email from HR confirming original acceptance and start date. She is at a losss what to do, and still awaits the letter, but her emails are being ignored by the HR representative.  Whilst not exactly fair play on the employers part, can anyone see the best way forward here?  Thanks in advance.
