Nice one Rich, will bell them 2moro.
I'm sure my lads swing the lead at some point, and that's the nature of employees generally, tracker will be good to use for assisting them regarding locations of some jobs, sorting round orders to run a more economical route.
I find there has to be a little give and take in terms of times starting and lunches, provided the work gets done of course. It gives you leverage if there are any problems in the future, and with e tracker, you at least can back it up, so they know you are on their case should they take the p.
