Especially in our business of a thousand details, being late is unforgivable. In my experience, the only way to ensure everything gets done in time is religious observation of routine. As soon as someone is late, everyone else has to cover the slack, and the inevitable result is that productivity suffers and details are missed.
It may sound harsh, but if you're not going to come on time, don't come at all. Let me find someone else who will.
Now, I am speaking from the perspective of an opener. I have a very strict deadline that my team, both FOH and preppers, have to hit every day. There is no negotiation about what time my business opens.
I'm interested to know if people find the same stringency is necessary with night staff, who are relieving their counterparts. If you had a really talented individual who was chronically late, what would you do about it?
