Hi Paul, not at all tiles should always be laid on a solid base of adhesive otherwise with a little weight they will crack,if you had a reputable tiler he should have known this.regards john select floors

No. Floor tiles are rigid and will crack when pressure is put on them across the dob/dab adhesive. As a example, if you lay a 600mm tile across a piece of 19mm wood baton and stand with one foot at each end, the tile will break. Floor tiles must be laid on a solid bed of adhesive. This is typically spread across a floor using a 10mm comb tiling trowel. The tile is laid, pressed into place with a slight twist to ensure the adhesive spreads out into a solid bed of tile adhesive under the tile. Your floor will need to be taken up and relaid properly.
