If you are struggling to recruit, ask yourself these questions:
How much of this job can be done from home?
Can we accommodate part-time or flexible hours?
Does this job need to be done by only one person?
If you are honest with yourself, these answers may take you out of your comfort zone yet present new ways to access excellent candidates.
Stay at home mums and dads, people limited by school times, people with individual needs that preclude a 9 to 5 day in the office.
All of these people may be ideal candidates if you can accommodate what is to them non-negotiable, while for you entirely negotiable.
If you can't accommodate their needs, you'll need to look at other avenues to fill your vacancies.
If you won't accommodate their needs, you're limiting your ability to recruit.
