DH has made a flexible working request and the 14 days have now passed with no response at all.
What should he do now?
He does not have very good relationship with his manager, she has been very obstructive in the past (refused on 3 seperate occasions to let him book a days annual leave to take seriously DSS - who is DH's 10 year old - to Great Ormond Street etc) so DH feels the need to be more formal than just a friendly call or email.
Is there a recommended route to go down if a manager does not respond within the 14 days? Should he go straight to the manager above her, or tell HR, or go to the union?
