How long do we have to give the employees to sign a new company policy? Ie. 1 day, 2 days??

There’s no statutory or regulatory requirement that employers have employees sign a new company policy before it can take effect. To the extent such a rule exists, it would have to come from the contract or company policies themselves. In addition, if you’ve made it a practice to get employee sign-off to new policies in the past, you may be required to continue doing so in the future. These principles apply not just to the need to get sign-off but also the deadline for doing so. Hope this helps. Glenn.
