Flexible working is not new, however, if you knew that you could get the right candidate with the right skills, who could only commit to working for you for 4 days and not 5 days and is likely to outperform your employees who work 5 days a week, then why not put them through the selection process and have a more flexible approach to your recruitment strategy. What have you got to lose? Candidate are attracted to companies that have a more flexible approach to working and in return work hard to prove that working flexibly has a positive impact on your business. Give it a try.
