hi ya,
ive been on a hell of a journey via smp ma tax credits redundancy etc etc, if you have worked for your employer for 26 weeks into the 15th week before your baby is due then you qualify for smp...if you have had time off during your pregnancy for "pregnancy related problems" then they are not able to use this sickness period against you and it cannot be disclosed to any future employers via references etc, there is a tool on the directgov wesite called the tiger tool aswell as an inland revenue smp calculator, you put in your dates you started work, sickness, pay dates etc and it calcultaes it all for you *this site is where your employer will go to find out all the details*
