Absolutely definitely NOT! Good grief!!
You could make out a case for having a lookout that gets all vehicles and people to vacate to the outside edge of the Cleared & Graded Area whilst an a/c operates, but then only if ATC receive notification that this has happened before giving 'clear to land' to anyone. You could also have intersection departures provided a risk assessent and method statement had been put in writing first. We occasionally do this, typically with about 500 metres for 737/A320 departures up the runway from the works, but definitely NO landings over work on the runway or even in the undershoot by 2-300 metres. Landings/takeoffs towards WIP require not only TORA & TODA but also RESA up to the works.
Look at accidents with WIP in runways in Taiwan and the hampering of the aid effort when an a/c struck animals on a runway in Indonesia.
I know it's very difficult if you move to a job where there is a very different culture but it sounds significant that no-one's put the instruction in writing...
