Talky I am slightly concerned how you are interpreting the information you are finding. I have quoted directly from ACAS website about flexible working applications below -
"How must the employer respond to the applicant?
In order to comply with the procedural requirements the employer must:
arrange a meeting with the employee within 28 days of receiving the application to discuss the request. This meeting is not required if the employer agrees to the terms of the application and notifies the employee accordingly within 28 days of receiving the application
allow the employee to be accompanied by a work colleague if they so wish
notify the employee of their decision within 14 days of the date of the meeting. This notification will either:
? accept the request and establish a start date and any other action or
? confirm a compromise agreed at the meeting, or
? reject the request and set out clear business reasons for the rejection together with notification of the appeals process
arrange to hear the employee's appeal within 14 days of being informed of the employee's decision to appeal. The employee must be allowed to be accompanied by a work colleague if they so wish
notify the employee of the decision on the appeal within 14 days after the date of the meeting. The notification will either:
? uphold the appeal, specify the agreed variation and start date or
? dismiss the appeal, state the grounds for the decision and contain a sufficient explanation of the refusal."
As you can see, as I mentioned before, it is a legal requirement to meet to discuss an application and the meeting has to be arranged within 28 days of receiving the application. They then have to notify you of the decision within 14 days and give you the right to appeal it. Nowhere does it say they have to inform you in writing in 7 days.
