yeah, you should be able to push the piston back into the slave about a quarter inch. if you can't push it at all, then you need to adjust your clutch pedal so that there's some slop in the pedal before it actually starts moving fluid, not tightening it up. basically i think you have it too tight and it's half way pressing on the fingers of the flywheel, thus cauing your clutch to slip.

if you cannot push on the fork against the slave cylinder and push the piston of the slave cylinder in at least 1/8" after giving the pedal some slack then you need to replace your clutch master cylinder.
