Best practice
Always use the singular form "effect" after "have an" to ensure grammatical correctness. For instance, say "The policy will have an effect on productivity", not "have an effects".
Common error
The word "effects" is typically used as a plural noun or as a verb meaning to bring about. Avoid using "effects" after "have an"; instead, use the singular noun "effect". Remember, you can use "affect" (verb) to describe influencing something, but not after "have an".

When should I use "affect" versus "effect"?
"Affect" is typically used as a verb meaning to influence something (e.g., "The weather will affect our plans"). "Effect" is typically used as a noun meaning a result or consequence (e.g., "The medication had a positive effect"). Consider using "have an impact" as an alternative.
