Flexibility is such a topical word but what does it really mean? Who wants it and how do you get it?

Salaries are not just about money – your renumeration is called a package as it consists of all the attractive, enticing temptations to draw you in to a new role and keep you there.

Flexibility is one word I hear bandied around at negotiating stage. It demonstrates that an employer is supportive, compassionate and open to an employee's personal requirements. It is something the employee can request without "perceived cost" and is considered a perk. Employees want it, and employers wish to allow it but they all find it frustrating when the structure is not clearly defined.

So what is it and how do you get it?
