FAQs
How do I use "on a flexible basis" in a sentence?
You can use it to describe how a task or job is performed, for example: "The consultant was hired <a href="/s/on+a+flexible+basis" target="_blank" rel="alternative">on a flexible basis to help with the transition."
What is the difference between "flexibly" and "on a flexible basis"?
While both mean the same thing, <a href="/s/flexibly" target="_blank" rel="alternative">flexibly is a concise adverb, whereas "on a flexible basis" is often preferred in formal contracts or business reports to sound more definitive and structured.
Can I say "on a flexible schedule" instead?
Yes, if you are referring specifically to time. Use <a href="/s/on+a+flexible+schedule" target="_blank" rel="alternative">on a flexible schedule if the variability concerns hours, but use the original phrase if the flexibility covers broader terms like duties or locations.
Is "on a flexible basis" formal enough for a CV?
Absolutely. It is a professional way to indicate that you are open to different working hours or that a previous role was not a standard full-time position. You might also consider <a href="/s/available+for+flexible+work" target="_blank" rel="alternative">available for flexible work.
