Many of your staff communicate in different ways to each other and would probably welcome easier access to managers and work updates if they were communicated in a way familiar to them.

For example, is the staff roster pinned up on a wall somewhere at work? Why not text it direct to their cell phone, there is plenty of software out there to facilitate this.

Can their pay checks be emailed direct to them instead of in an envelope?
How about allowing training videos to be viewed at home or in their own time, instead of in group sessions at work?

Stay in touch with your staff, work smarter.
