Sack the project manager. If he can't lay a straight edge onto a floor before asking a tiler to tile on it then the shouldn't be doing the job. Sorry - but you really did ask for it. You level the floor THEN lay the tiles. You were the boss - he was your employee.
Seeing as its getting late and im losing my tolerance to people wanting a bit of attention on here, i may as well reply to this loser, although i guess mum has tucked him into bed long ago.
PM's manage projects correct? My partner has done a dam good job managing this extension, but it's somewhat reliant on honest tradesmen, when we're told the screed is 'dead flat' then 3 tilers quote and not one queried the level of the floor, you sort of take the assumption it must be level and even? We hired a tiler to tile the floor, which includes being able to make a decision on wether such surface is suitable or not.
I wouldn't build a pc on a ****ed hard disk id check it first! And thats if i was being paid 30 or £300 pounds.
Jefoss, yes i asked him why when he thought the floor was uneven did he not call me. He said "well it was a bit late before i realised as i was already halfway through"
Honestly though, i think the issue is just poorly laid, ive checked the lounge (done by same screeder) with a 2metre level and it's pretty dam good, there's a slight gradient, he warned me about but it's very flat.
In tilers defence he's trying to sort it, but ive lost all confidence. We argued over a tile earlier which i felt was impossible to rectify as the tiles either side were at different levels, which meant you would of had to twist the tile to be flush both ends, no digging out of the floor would rectify that imho.
Life is more important than this i know!!! Its just the principle, i saved up £1500 to have our kitchen floor perfect, and it's far from it.
