Do You Have Your “To Do” Compliance List Ready for 2024?

Ah fall.  Many enjoy the foliage (though not so much the leaf raking that goes with it).

In the world of HR, fall also means planning.  There are budgets to be finalized and adopted, but there is also the need to identify the key compliance items to not lose sight of in the upcoming year.

What should be on your radar? 

First, if you haven’t already done so employers MUST use the most recent Form I-9 (with the 8/1/2024 revision date).  Older versions are no longer accepted as of November 1stTo view and download the 8/1/2023 Form I-9 – click here.

For Massachusetts employers, there is the need to ensure updated Massachusetts Paid Family and Medical Leave notices and posters remain current.  Connecticut employers must account for communicating and distributing to employees notice on their rights under the Connecticut Family and Medical Leave law.

So, as you can see, if you haven’t done so, make sure you grab a 2024 calendar and have it ready.  It is now time to fill it up and plan for the coming year.
