Description: Game won’t let you send other employees on vacation, when their bars are low, after hiring new employees.
Version Happened: TB 1.3.9

Not a bug.

The lowering of the bars are to show decreased employee efficiency. This efficiency can come from one of two things: The need for a vacation and/or a new team member. If the bar is there due to a new team member, you can’t just send them away on vacation to make it recover as it represents the disruption to the team that new blood creates.

However, there is a trick to get around this (a trick which probably is a bug)

If you wait until your employees start to show the bars due to needing a vacation and THEN hire your new employee(s) You’ll still be able to send them on vacation. During which they’ll recover all the efficiency lost from needing a vacation AND all the loss from the new employees. They’ll be back to full before your character and the new hire.
