Last boss i had , 50 men construction company , had one old van that he owned private , for employees to use for private things like moving stuff . You just had to put your name one a date on the calendar in the break/lunch room . For special equipped van's the boss was always willing to make fake entry's in his log's . The workplace , fully equipped was after company hours always open to employees that had some technical private stuff to fix , even for private trade . As long as you where honest , wrote down the resources you used of him and where willing to pay them . Mostly he never claimed the cash do , saw it as advertisement , and gave him room for bigger jobs , for most locals had there little technical problems solved by someone in not his time .

Now i hope not that some grey midwit reads this and send's the tax squad at them . Just because someone is creative , uses his skills , and makes a nice looking steel garden fence for his neighbor or friend ,.. doing the works , earning some cash or trade it for skills that an other has ,.. on the side , in his own time . ;-)
