Do I have to tell employees before the sale closes?

Sellers worry about this constantly, and understandably — telling staff too early risks losing key people to competitors before the deal even closes, while telling them too late feels unfair and can damage the culture the buyer is paying for. There is no single right moment, but there are real constraints on both ends.

Why confidentiality usually wins until signing, or later

Most sale processes are kept confidential from staff until an agreement is signed, and sometimes until closing itself, because a deal that becomes public and then falls through can damage the business, unsettle customers, and prompt exactly the staff departures everyone is trying to avoid. Confidentiality provisions in the purchase agreement typically reflect this directly.

Where the legal picture changes

A unionized workplace can carry its own notice or bargaining obligations under labour relations legislation once a sale is far enough along to affect the bargaining unit. And where the deal is an asset sale, employees need real notice of any new offer of employment and enough time to actually consider it — that is a practical and legal necessity, not a courtesy, because it goes to whether they meaningfully accepted new terms.

What tends to work well in practice

• Confirming the deal, then telling employees as soon as it is signed rather than leaving them to hear it elsewhere
• Having the buyer and seller agree in advance on who communicates what, and when
• Giving employees who will receive new offers enough lead time to review them properly
• Preparing a simple, honest explanation of what is and is not changing for them

The cost of getting the timing wrong

Staff who learn about a sale from a customer, a supplier, or social media before hearing it from ownership tend to disengage or leave, and a business that loses key people between signing and closing can jeopardize the deal itself. Silence is not free even when it is not legally required.
