Work anniversaries are available for paid plans only. Let's head up the link to unlock them https://birthdaybot.io/pricing/.
Please note that only BirthdayBot admins can set hire dates. By default, the user hire date will be the day the bot was added.
To set a specific hire date, let's find BirthdayBot under the Slack Apps section and open on its Message tab. Dm the bot with hire dates.
A new modal window will open up. Please, find a drop-down box there, specify Unknown Hire Dates, and hit the Set Hire Date button.
This will take you to a pop-up window giving you a chance to set a hire date.
