Disciplinary for sick, stores?

[Nomad]

due to the union campaigning against the first version of SYA in stores  it was amended.

Those who have an absence over 3% or 3 absences in a 26 week rolling period have an attendance review investigation.
If there are no mitigating circumstances (this doesn't include sick notes) then there are several possible outcomes:
No further action, Next steps or a disciplinary for failing to fulfill your contracted hours are the most usual ones.
At no point are there stages or overtime bans. (though the company will argue that by denying overtime they are ensuring you can fulfill your contracted hours and are looking after you)

The disciplinary stage is started by a verbal, if during that period you are off again you may receive a first written, further absence and then a final written, followed by what could be dismissal.
The stages of the actual disciplinary can be jumped.
e.g. if you have had 2 writtens previously that have expired, and you have 0% absence in the last 26 weeks but go off again causing your % to increase to over 3%, they can decide  that you need to bypass the verbal and first written warnings and move straight to a final, as the previous warnings have not had the desired effect and that the system might be being played.
