in QBO payroll list of employees - a few employees have a green dot beside their name. What is the significance of this?

I can share some information of what's the significance of the green dot beside your employee's name in QuickBooks Online Payroll, @linda115.

You can use the Who's Working window to know the different statuses of your team members.

Here's how:

1. Sign in to your QuickBooks Online account, and select Time.
2. Click on Time team, then Who’s working. 

You can determine your team member's current status through this:

• Green dot: On the clock
• Orange dot: On a break
• No dot with worked time displayed: Not on the clock, but worked earlier today
• No dot and no time displayed: Not on the clock and hasn't worked today
