If you work in a community shop, it might be good idea to establish a new rule with regard to machinery that's set to other than 90 degrees: Anyone who uses a table-saw (for instance) at 89 degrees, is expected to crank it over to some angle that's more visibly off square (such as 75 degrees), so the next person can see that it's off,and be responsible for squaring it up. I've worked in a community shop that followed this rule, and it works surprisingly well.
